Reclining device of seat for vehicle
[19] The present invention relates to a seat reclining apparatus for an automobile, and more particularly, to the provision of an improved reclining apparatus that satisfies a law for fixing a three-point seat belt to a seat.
[20] The seat of the vehicle is to maintain the occupant attitude of the vehicle occupant is further provided with a reclining device to adjust the angle of the backrest to the front and rear to fit the body of the driver and the occupant or the occupant to rest.
[21] The conventional reclining apparatus 1 will be described with reference to FIGS. 1 to 3.
[22] Free rotation is possible by the cushion frame constituting the vehicle seat 2 and the cushion frame holding the seat back 4 and the shaft 6 via the shaft hole 5 formed at the center fixed to the seat back frame. The plate holder 7 and the upper bracket 8 are provided.
[23] The lock gear 9, the cam 10, and the cam plate 11 are sequentially inserted into the space between the plate holder 7 and the upper bracket 8, and the lock gear 9 is an operating lever 12. ) And the gear tooth 13 formed on the lock gear 9 by the cam 10 and the cam plate 11 fixed and interlocked with the shaft 6 is formed inside the upper tooth bracket 8 ( It is to be reclined by being connected to and detached from 14).
[24] Of course, the actuating lever 12 is located on the outer side of the plate holder 7 can be returned by the lever spring 15 and the return spring (16).
[25] Recliner of the prior art as described above is composed of a plate holder having an extremely thin thickness (about 2 mm) and the important components necessary for reclining inside the upper bracket.
[26] In the case of this type, when the seat belt is fixed to the upper body and the floor as in the present case, even if the impact force due to collision or collision is conducted, the seat belt is not significantly transmitted to the entire seat as well as the reclining apparatus, thereby greatly affecting safety. It is true that it is not crazy.
[27] When the seat belt is fixed to the vehicle body as described above, the seat belt does not move together to fit the body of the rider, which acts as a significant risk factor. By institutionalizing the seat belt to be fixed to the seat to move together to keep the passengers in a safe state, the conventional technology can not satisfy the condition.
[28] As described above, when the seat belt is fixed to the seat, the impact force due to collision and collision not only acts greatly on the entire seat, but also significantly affects the reclining device that substantially fixes the seat cushion and the seat back. As a result, each component is separated.
[29] If the reclining device is detached as described above, the seat back may damage the occupant, and the seat belt restrains a part of the occupant's body. Several problems arise.
[30] Accordingly, the present invention is invented to solve the above problems, even if the impact force generated when the seat belt is fixed to the seat, the impact force generated when the impact on the whole sheet or reclining device to maintain sufficient rigidity to eliminate the phenomenon of each part By preventing it, it is possible to contribute to improving the quality and durability of the entire seat and the reclining apparatus, as well as to contribute to improving the safety of the passengers.

An exploded perspective view of an applied seat reclining apparatus for a vehicle, FIG. 7 will be described together as a configuration diagram illustrating a coupled state of the seat reclining apparatus for an automobile applied to FIG. 6.
[33] The reclining apparatus 30 to which the technique of the present invention is applied has a lower plate 31 and a seat back fixed to the cushion frame with a considerable thickness (about 6 mm or more) so as to maintain a stable state while the seat belt is fixed to the seat. An upper plate 32 fixed to the frame is provided, and plate holders 33 are fixed to both sides of the lower and upper plates 31 and 32.
[34] The plate holder 33 and the lower plate 31 are prevented from flowing with the fixing pin 34, and the plate holder 33 and the upper plate 32 are freely coupled with the folding pin 35 so as to freely move the plate. The return spring 36 mounted on the holder 33 is always pressed in a folded state.
[35] The upper gear 32 is formed on the lower outer periphery of the upper plate 32 by the lock gear 39 and the cam 40 inserted into the operation hole 38 formed in the upper center of the lower plate 31. Allow reclining and unclining to be selected.
[36] The operating holes of the operating lever 43 coupled to one side of the plate holder 33 through pin holes 42 formed in the plate holder 33 by protruding the operating pin 41 on both sides of the lock gear 39 ( 44).
[37] The actuating lever 43 is fixed together with the cam 40 by the lever pin 45 to move the actuating lever 43 to interlock the lock gear 39 together with the cam 40 to connect with the upper tooth 37. And reclining and unclining by disengaging.
[38] Of course, in the lock gear 39, it is preferable to form a connection groove 45 and a release groove 46 for connecting and detaching the cam 40 with the upper tooth 37, and the operation lever 43. It will be obvious that the lever spring 47 is connected between the plate holder 33 and the plate holder 33 to assist the return of the operation lever 43.
[39] The operation of the present invention as described above,
[40] When the initial state is viewed in a state where the lock gear 39 is engaged with the upper tooth 37, the cam 40 is positioned in the joint groove 45 of the lock gear 39 so that the lock gear 39 is connected to the upper tooth 37. ) Is in a state of continuing to engage with the state.
[41] When the reclining is to be performed in such a state, the cam 40 fixed together with the actuating lever 43 moves to the release groove 46 of the lock gear 39 by pulling the actuating lever 43. An actuating hole 44 formed in the lever 43 lowers the actuating pin 41 of the lock gear 39, and as a result, the lock gear 39 moves downward in the actuation hole 38 formed in the lower plate 31. By moving, the lock gear 39 and the upper tooth 37 are separated.
[42] Therefore, since the upper plate 32 can be freely moved, the position of the seatback can be freely adjusted. In the process of adjusting the seatback as described above, the user must hold the operating lever 43 continuously.
[43] The cam 40 moving together with the actuating lever 43 locks by the lever spring 47 returning the actuating lever 43 to its original position by releasing the actuating lever 43 in which the seatback adjustment is completed by the above operation. The lock gear 39 is engaged with the upper teeth 37 by being coupled to the connecting groove 45 of the gear 39, thereby limiting the movement of the seatback.
[44] In another example of the present invention, a lower tooth 50 is formed on the upper outer periphery of the lower plate 31, and the lower plate 31 is formed to be recessed in the pair of upper plates 32 coupled to the lower plate 31 and the fixing pin 51. The lock gear 39 is inserted into the lock guide 52.
[45] The actuating pins 41 protruding to both sides of the lock gear 39 are exposed through the pinholes 42 of the upper plate 32, and then the actuating holes of the actuating lever 43 coupled to one side of the upper plate 32. The lock gear 39 may be connected to and detached from the lower tooth 50 by the operating lever 43 so that the reclining and the unreclining may be performed.
[46] In the present invention as described above, since the thickness of each component constituting the reclining apparatus 30 is sufficiently thick, the size of the lock gear and the upper tooth gear that maintains the actual locking state can be increased, thereby increasing the bonding force. The condition is satisfied.
[47] Therefore, even when the impact force is transmitted under the condition that the seat belt is fixed to the seat, each component of the reclining apparatus 30 is kept in a solid state, thereby preventing the separation phenomenon, thereby increasing the de-stress for the break-up and deformation of the entire seat, thereby causing physical damage to users. This can be minimized.
[48] As described above, the present invention maintains sufficient stiffness even when the impact force generated when the seat belt is fixed to the seat is transmitted to the entire sheet or the reclining apparatus, thereby preventing the detachment of each part. It is an invention that has many expected effects such as not only contribute to the improvement of the quality and durability of the device, but also contribute to the improvement of the safety of the passengers.
