    Description
    Title of the invention: Bicycle saddles [0001] Reference to an associated request [0002] This request claims the benefit of provisional request US 62/740 348, entitled "Bicycle Seat Designs", filed on October 2, 2018, the subject is incorporated here in its entirety.
    FIELD OF THE INVENTION The present invention relates generally to bicycle saddles or other vehicles powered by pedals, and more specifically bicycle saddles which are both comfortable and which provide good support.
    Background of the invention [0005] Common bicycle saddles are not well designed for the human body. Sitting on a bicycle saddle causes tissue and organ compression and limits blood flow to the perineum area. Excessive pressure on the ischial tuberosities (TI or "ischions") causes discomfort for prolonged periods. Convex stools also tend to apply pressure and separation forces to the iliac bones. The static nature of these saddles causes friction and friction at the transition between a body and a saddle. All of these issues cause comfort and possible long-term medical problems for cyclists.
    Summary of the Invention The present invention provides bicycle saddles that improve the comfort of the cyclist. Bike saddles increase the saddle support area to distribute pressure and minimize extreme pressure points, while allowing the body and legs to move freely in a movement that promotes optimal biomechanics and power transmission to the pedals of the bike. Compared to conventional bicycle saddles, the bicycle saddles described herein have a larger and more streamlined area (curved into a convex surface) which gives a better distribution of pressure. In various embodiments, the saddle surfaces of the different saddle elements rotate in opposite directions for increased stability.

    Detailed description of the invention
    FIG. 1 is a perspective view of an example of a bicycle saddle 100, according to one embodiment. The illustrated bicycle saddle 100 has saddle elements 102, 106, a nose 110 and a support frame 112. The saddle elements 102, 106 and the nose 110 are separated and supported by the support frame 112. L the seat element 102 (106) has a surface 103 (107). The seat element 102 (106) comprises a pivot 104 (108) which connects the seat element 102 (106) to the support frame 112. The seat elements 102, 106 pivot forward and towards the rear with respect to the support frame 112. The support frame 112 includes a seat adjustment mechanism (not shown) and a saddle transmission mechanism (not shown). The saddle adjustment mechanism allows adjustment of the separation between the saddle elements 102, 106 to adapt to the anatomy of different users. The saddle transmission mechanism rotates the saddle elements 102, 106 in opposite directions. The saddle elements 102, 106 support in use the weight of a cyclist, unlike the nose 110. The nose 110 provides lateral stability, for example if the cyclist pedals as a dancer, when cornering or during aggressive maneuvers. The nose 110 is preferably strong enough to support the weight of the cyclist, at least for short periods. All of the components are described in more detail below.
    Saddle surfaces [0053] The saddle element 102 (106) has an ergonomically profiled surface 103 (107). Figure 2A is a perspective view of a surface of the saddle member 102, according to one embodiment. As shown, the seat surface 103 is concave in shape and provides support to a cyclist seated on the saddle member 102. The terms "cyclist" and "user" are used interchangeably herein. Compared to convex or flat saddle surfaces, the concave surface 103 provides increased area to reduce pressure on a surface that causes discomfort during prolonged use. The movement of the hips and legs causes the seat element 102 to pivot forward and backward relative to the support frame in order to maintain maximum surface contact for significant pressure relief. For example, as illustrated in FIGS. 3A to 3D, the seat element 102 pivots forward and backward so that the surface 103 maintains contact with a hip and leg area of a cyclist . Figures 3A to 3D show different phases of a pedaling cycle. To improve the pivoting of the saddle, the pivot pin can be placed behind the center of gravity of a seated cyclist. The center of gravity is usually located in the maximum load area or at the IT level. An example is shown in Figure 3E. The pivot axis 352 is located behind the position of the ischia 354.
    To ensure comfort and good support, the saddle elements preferably provide larger areas of contact with the cyclist. As the saddle elements pivot when the cyclist pedals, the saddle elements can be given dimensions which would hinder the cyclist's pedaling if the saddle elements did not pivot. In some models, the saddle element has an overall length of at least 60 mm, and an overall width of at least 120 mm (on both saddle elements).
    Returning to FIG. 2A, the surface 103 is elongated at the level of the front surface with a progressively softer leading edge 206 which allows a larger area, and better contact with the saddle to ensure rotation. Without this soft transition zone on the thigh, the high-speed rotation / oscillation of the saddle is not as effective. This area also reduces the stress line in front of the saddle surface for added comfort. A saddle element may be provided with saddle padding which provides additional grip and comfort, as well as stability. An example is shown in Figure 2B.
    Figure 2B is a perspective view of a seat pad 250, according to one embodiment. The seat pad 250 can be attached to or detached from a saddle element. Different seat pads can be used for different types, types or body types of cyclists. The seat pad 250 keeps the user in place and prevents them from sliding forward during a forward rotation, in particular at the transition region 252 between the gluteal muscle and the hamstring muscle. Preferably, the seat pad 250 does not interfere with the hamstring muscle or tendon.
    Adjusting the saddle elements Users can adjust the saddle elements, for example the separation between the saddle elements. The separation of the saddle elements 102, 106 can be adjusted to adapt to the geometry of the pelvis and to reduce the stress exerted on the cartilage of the pubic symphysis. FIG. 4A is a perspective view of the example of saddle 100. As previously described, the saddle elements 102, 106 have concave surfaces. The distance 401 is the distance between the parts of the saddle element 102 which support the ischial tuberosities, or TL The distance 401 can be adjusted to adapt to the geometry of the pelvis. FIG. 4B is a perspective view of the example saddle 100. The distance 402 is the lateral separation between the opposite edges of the saddle elements 102, 106. The lateral separation 402 can be adjusted to substantially eliminate the stress exerted on the cartilage of the pubic symphysis which holds the pelvic girdle. The separation stress is caused by the surfaces of conventional convex bicycle saddles which separate the TLs In FIG. 4B, the saddle elements 102, 106 are separated in a wider manner than in FIG. 4A.
    In the example of Figure 4, the saddle 100 includes a mechanical screw separation mechanism 410 which can be used to adjust the distances 401, 402. Figures 4C and 4D are plan views of the mechanism mechanical separation screw 410 respectively in an enlarged state (greater separation of the saddle elements) and in a compressed state (low separation of the saddle elements). In the example illustrated, the passage between the different states of the mechanical screw separation mechanism 410 can be adjusted by turning the central screw 412. The rotation of the central screw 412 clockwise (or in the opposite direction) widens (or compresses) the mechanical screw separation mechanism 410, which increases (or reduces) the distances 401, 402.
    In some embodiments, in a seat element 102 (106), the relative position of the pivot 110 (or 112) can be adjusted. FIG. 5 illustrates the adjustment of the relative position of the pivot 104 in the saddle element 106. As shown, a contact closure is present between the saddle surface 107 and the pivot 104. A bottom 502 of the saddle surface 107 comprises contact closure hooks (+) and the upper surface of pivot 104 includes loops (-). The pivot 104 can be separated and fixed to the seat surface 107 by means of the contact closure. When fixed, the upper surface 504 of the pivot 104 is in contact with the lower surface 502 of the saddle surface 107. The adjustment of the relative position of the pivot 104 (or 108) in the saddle element 102 (or 106) can itself adjust the distances 401, 402. The separation of the saddle surface from the pivot also allows users to replace the saddle surfaces with different profile levels. Modular saddle elements offer flexibility and customization possibilities. Users can install different saddle elements on a support frame. In certain embodiments, sliders are used for adjusting the separation of the saddle elements 102, 106. FIG. 6 represents the adjustment of the relative position of the pivot 104 in the saddle element 102 by the through a slider 604. As shown, the bottom surface 602 of the saddle surface 103 includes a slider 606. Specifically, the top surface 604 of the slider 606 is fixed to the bottom surface 602 of the saddle surface 103. The pivot 104 has a groove 607 intended to receive the cursor 606. By sliding the cursor 606 in the groove 607, the relative position of the pivot 104 can be adjusted. The adjustment of the relative position of the pivot 104 (or 108) in the seat element 102 (or 106) can adjust the distances 401, 402.
    In some embodiments, a sliding mechanism is used to adjust the separation of the saddle elements 102, 106. FIGS. 7A to 7C illustrate the adjustment of the relative position of the pivot 104 relative to the support frame 112 In the example illustrated, only the axis of the support frame 112 is shown. As shown in FIG. 7C, three screws 701 can be fixed to compress the bore of the pivot 104 on the support frame in order to secure the pivot 104 to the support frame 112. The loosening of the three screws 701 allows the pivot 104 to slide along the support frame 112 in order to adjust the distances 401, 402. For example, relative to the position of the saddle element 102 of FIG. 7A, the saddle element 102 is more away from the center of the support frame 112 in Figure 7B.
    Transmission of the saddle In various embodiments, the saddle elements 102, 106 pivot in the opposite way: they pivot in opposite directions. The support frame 112 includes a transmission system which causes the seat elements 102, 106 to pivot in an opposite manner. The purpose of this “counter-pivot” is to: 1) imitate the natural cycle of movement of the legs during pedaling , and 2) provide a feedback that allows the user not to accidentally slide out of the saddle (action-reaction). In various embodiments, the transmission system may include a differential, a mechanical link or a cable link. When pedaling, when one leg goes down, the other leg goes up. The profile of the seat surfaces corresponding to the rising leg provides most of the forward stability. By rotating the saddle elements in the opposite direction, the sliding of the pelvis forwards is reduced. This provides additional stability to the pelvis during the rotation cycle.
    Figures 8A and 8B show the saddle 100 having a differential 800 to rotate the saddle elements 102, 106 in an opposite manner. The support frame 112 comprises the differential 800 as part of a transmission system . The support frame 112 also includes axes 802, 804 which respectively rotate the saddle elements 102 and 106. The differential 800 couples and counter-rotates the axes 802 and 804. Specifically, the trains of coaxial gears 806-809 rotate the axes 802, 804 in opposite directions. The counter-rotation of the axes 802, 804 causes the seat elements 102, 106 to pivot in an opposite manner. FIG. 8B is an enlarged view of the differential 800.
    FIG. 9A is a line drawing illustrating a mechanical connection 900 for pivoting the seat elements 102, 106 in an opposite manner. The support frame 112 comprises the mechanical connection 900 as part of a system of transmission. The mechanical connection shown 900 comprises bodies 901-903 connected at the level of articulations 905, 907. The body 901 is connected to the saddle element 106 via the articulation 910, and the body 903 is connected to the element of saddle 102 via the joint 911. The bodies 901 and 903 move in opposite directions due to the pivot 906. In the example illustrated, the joints 905 and 907 are sliders. The joints 910 and 911 are hinges.
    Figures 9B to 9D illustrate different positions during the operation of an example of mechanical connection 900. Figure 9B shows a "neutral" position of mechanical connection 900. The bodies 901, 903 overlap substantially vertically. The saddle elements 106, 102 are substantially in the same plane, which is parallel to the ground. FIG. 9C represents an extreme pivoting state of the mechanical connection 900. The body 901 is higher than the body 903. The body 901 moves upwards and the body 903 moves downwards, which makes it pivot opposite the saddle elements 106, 102. Similarly, FIG. 9D illustrates the opposite pivoting state of the mechanical connection 900. The body 901 is lower than the body 903. The body 901 moves downwards and the body 907 moves upward, which causes the seat elements 106, 102 to pivot in an opposite manner.
    FIG. 10 illustrates a cable connection 1000 for pivoting the seat elements 102, 106 in an opposite manner. The clip 1001 (1002) of the cable connection 1000 is connected to the lower surface of the element. saddle 106 (102). The cable 1000 can be enclosed in a sheath 1003. When the right leg of a user presses down on the front part of the saddle element 102, the saddle element 102 moves down and pivots towards the 'before. Cable 1000 raises and pivots seat element 106 backwards.
    Adjusting the inclination In certain embodiments, an inclination of the saddle elements can be adjusted by a cyclist. The tilt of the saddle surfaces can be adjusted to reposition a user's pelvis if the user adjusts its position. Figures 11A to 1 IC illustrate the adjustment of an inclination of the saddle surface. The inclination of the saddle surface can be measured by the angle 1102 relative to the ground, which reflects the forward inclination of the body and the pelvis. For example, the tilt swings forward (back) and the angle 1102 increases (decreases) for a more sporty and efficient position (straight and relaxed). Figure 11A shows a more upright position and a less inclined saddle. Figure 1 IC shows a more aggressive position and a more inclined saddle. Figure 11B is in between. As previously described, the saddle has a transmission system which can implement different ways of pivoting the saddle elements in an opposite manner. The adjustment of the inclination of the saddle elements is further described in relation to FIGS. 12 to 15. In various embodiments, the cyclist can adjust the inclination of a saddle element while riding.
    Figures 12A to 12D illustrate the adjustment of the inclination of a saddle element in a transmission system which includes a differential. The differential 800 is coupled to a slider 1200. The position of the slider 1200 can be adjusted in order to adjust the inclination of the saddle element. The position of the cursor 1200 can be adjusted by hand as illustrated in FIG. 12B. In other embodiments, the position of the cursor 1200 can be adjusted by turning a screw 1202, as shown in Figure 12C. Tensioning or loosening the cable 1204 can also adjust the position of the slider 1200, as shown in Figure 12D. In some models (as in Figure 12D), the user can adjust the tilt of the saddle surfaces and / or the separation of the saddle elements while riding.
    FIG. 13 represents the adjustment of the inclination of a saddle element in a transmission system comprising a mechanical connection. By stretching the 1304 cable, the entire mechanism is pulled down. This implies that the saddle elements 102, 106 tilt upwards to return to a horizontal position. Conversely, slackening the 1304 cable causes the entire mechanism to rise. This implies that the saddle elements 102, 106 tilt down. A spring and a screw help to adjust the angle.
    Additional saddle settings [0074] Figures 14A to 14E illustrate the adjustment of a saddle element, according to one embodiment. In this example, the saddle elements 102, 106 can be rotated to adjust their separation. Figure 14A shows a top view of the saddle and Figure 14B shows the bottom view. In these figures, the saddle element 102 can rotate around a pivot point 1402. The position of the saddle is fixed by a piece
    1403 which travels along an arc 1404. For example, part 1403 can be a screw thread which aligns with slot 1404, with a bolt or other fastener that fixes the position. This mechanism allows a fan movement, as shown in Figures 14C-14E. In FIG. 14C, the saddle is configured for ischions having a separation of 110 mm. The width of the saddle is 132 mm. Figure 14D is for 125 mm ischia with a saddle width of 147 mm. Figure 14E is for 138 mm ischia with a seat width of 160 mm.
    Figures 15A-15B and 16A-16B illustrate lateral adjustments of a saddle element, according to other embodiments. Figures 15A and 15B show top and bottom views of a saddle with a saddle member 102 mounted. The lateral position of the saddle element is adjustable along the direction of the slots 1504, that is to say along the right-left direction. Seat element 102 may contain screw threads 1503, with bolts used to fix the position of the seat element.
    Figure 16A shows a top view of another saddle with a saddle element 102 mounted. Figure 16B shows a bottom perspective view of the saddle member 102. Figure 16C is an exploded view of the saddle. The lateral position of the saddle element is adjustable along two dimensions. The lower part has two slots 1604 along one direction, and the saddle member 102 has two corresponding slots 1603 along the perpendicular direction. This allows adjustment in both directions.
    Still other settings are possible. For example, as shown in FIG. 17, the saddle elements 102, 106 can be rotatable along an axis 1702, 1706 oriented along the front-rear direction. In other words, you can rotate the saddle elements to the right or to the left. This can be used to raise or lower the center of the saddle from the edges. If the right saddle element 102 is rotated to the right and the left saddle element 106 to the left, this raises the center of the saddle relative to the edges.
    Stability of the body and alignment on the saddle The nose 110 provides stability when cornering, and also guides the user in correct alignment and the correct position on the surface of the saddle. Cyclists lean on the front of the bike when cornering and in aggressive maneuvers to achieve stability because the saddle can come into contact with the inner thighs. The nose of the saddle also provides a guide to properly align the body on the saddle after a change of position or a standing position on the pedals. The seat nose 110 and the seat surfaces 103, 107 form a gap under the perineum region of a user. This gap reduces pressure and minimizes friction to the perineum area to prevent discomfort and friction. In addition, the aerodynamic design reduces drag and increases air flow in the perineum area, improves comfort, and reduces humidity which can cause skin problems. The design of the saddle eliminates the need to wear a padded "short" that tends to absorb and retain moisture and heat that causes discomfort and skin problems. Soft materials can also be used in this gap region. This can give the illusion of a more traditional saddle while providing the same pressure reduction function.
    The saddles described herein can also be used in other vehicles powered by pedals, such as tricycles, unicycles, planes, pedal boats, nautical cycles, and similar vehicles.
