    Submarine Prevention Sheet
    The present invention relates to a submarine prevention sheet, and more particularly, to install a eccentric gear under the seat, and in response to a signal from an airbag controller, an explosion device drives the eccentric gear to temporarily lift the seat, thereby causing a submarine phenomenon during a crash. It relates to a submarine prevention sheet that can prevent.
    In general, the car seat is adapted to the driver's body to operate in an optimal state. That is, an apparatus for adjusting the cushion sheet in the front-rear direction and the vertical direction or adjusting the angle of the seatback to fit the body of the driver has been proposed.
    However, the vehicle seat of the general structure has no countermeasure as a device for safety at the time of collision.
    That is, during a vehicle crash, a so-called submarine phenomenon occurs in which the seat falls to the floor at a time due to the impact. This is a very dangerous situation that not only protects the driver or passengers safely, but also makes it difficult to escape passengers from the accident vehicle safely and quickly in the event of a fire caused by a collision.
    Accordingly, an object of the present invention is to install a eccentric gear under the seat, and prevent the submarine which can prevent the submarine phenomenon during a collision while the explosion device drives the eccentric gear to temporarily lift the seat according to the signal of the airbag controller. In providing a sheet.
    1 is a block diagram showing a submarine prevention sheet of the present invention.

    The submarine prevention sheet of the present invention for achieving the above object relates to a submarine prevention sheet, wherein at least a seat for a passenger to sit on, a cushion frame mounted under the seat, a track and a seat installed under the seat to adjust the seat A seat structure including an adjustment lever, comprising: a bracket provided on the section frame, a height adjustment link installed on the bracket so as to be movable on a hinge axis, and a rolling bar on the height adjustment link. An eccentric gear installed through the eccentric gear and an actuating gear connected to the explosion device, the explosion device comprising a squib as an inflator-type ignition device, a booster charger and a propellant which are exploded in series reaction to the squib, a return spring, It consists of a piston and is electrically connected to the airbag controller.
    Therefore, in the event of a vehicle crash, the squib, booster and propellant are exploded to operate the piston and the eccentric gear is temporarily lifted to prevent the so-called submarine phenomenon. It is effective to protect it safely.
    Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
    1 is a block diagram showing a submarine prevention sheet of the present invention. Reference numeral 10 denotes a front seat, and 20 denotes a section frame mounted below the front seat 10. Bracket 30 is provided in this section frame 20, and the bracket 30 is provided with the height adjustment link 40 which can adjust the height of a sheet | seat so that the hinge shaft 42 is movable. .
    A rolling bar 50 is fixed to the height adjustment link 40, and an eccentric gear 60 is provided at the end of the rolling bar 50.
    The eccentric gear 60 is engaged with an operating gear 62 which is operated by the explosion device 80 of a predetermined configuration.
    The explosion device 80 is electrically connected to the airbag controller 70, and a booster charger that explodes by chain reaction with a squib (inflator-type ignition device) 82 and the squib 82. It consists of a charger (84) and a propellant (propellant) 86, a return spring 88 and a piston 89.
    Reference numeral 90 denotes a track installed below the sheet 10 to adjust the sheet, and 92 denotes a seat adjustment lever.
    The submarine prevention sheet of the present invention configured as described above, when the accident occurs, the squib 82 is exploded by a signal input from the airbag controller 70 and the booster 84 and the propellant 86 by this force. ) Explodes in series at high temperature.
    Subsequently, the piston 89 is momentarily extended to the outside by the exploded and combusted high pressure to push the operating gear 62 installed at the end of the piston 89. Since the operation gear 62 is engaged with the eccentric gear 60, the eccentric gear 60 is pushed up to the position of the uppermost position.
    Therefore, the rolling bar 50 is lifted and lifts the front seat 10 on the cushion frame 20 by lifting the bracket 30 through the height adjustment link 40.
    As a result, the seat is prevented from sitting down by the command of the airbag controller 70 that controls the airbag during the vehicle crash.
    As described above, according to the submarine prevention sheet of the present invention, when the vehicle crashes, the squib, the booster and the propellant are exploded based on a signal from the airbag controller to operate the piston and drive the eccentric gear to temporarily lift the seat. Thereby, there is an effect that can prevent the so-called submarine phenomenon to protect the passengers safely.
