Detailed description of the invention
1 to 2 detailed description of the invention of the present utility model is described further by reference to the accompanying drawings:
A kind of triple protection safety chair seats of car, comprises slide mechanism, flap actuating mechanism and chair back regulating mechanism.Seat is fixing on the sliding mechanism by riser, and slide mechanism is fixed on chassis of vehicle body, riser and the symmetrical parallel setting of slide mechanism.Chair back regulating mechanism is arranged on seat side, and seat front is provided with flap, and flap connects flap actuating mechanism, and flap actuating mechanism connects slide mechanism.Slide mechanism makes seat unidirectional slip backward after auto against, and slide mechanism slides backward and drives flap actuating mechanism that flap is turned down, and chair back regulating mechanism removes the locking of the chair back, triple action general protection driver and crew.
Seat is fixing on the sliding mechanism by riser 2, and slide mechanism is fixed on chassis of vehicle body by the footing 32 of slide rail 31.With seat cushion 9 on seat, trisection line place, seat front left and right is provided with the flap 10 that can turn down downwards.The riser of the symmetrical parallel setting of seat, slide mechanism and pad anvil are positioned at not foldable seat two bottom sides in the middle part of seat.
Slide mechanism 1 comprises slide rail 31, slide rail 31 has two parallel tracks, dentation draw-in groove and poroid draw-in groove 12 is provided with inside track, dentation draw-in groove is connected with L-type limiting card 30, L-type limiting card 30 is rotatably connected to the adjust bar 28 of manual regulation seat fore-aft position, in adjust bar 28 two-arm, axle is connected with single direction ratchet 11, and the ratchet of single direction ratchet is connected in poroid draw-in groove 12, and the rear end of adjust bar is fixed on seat riser 2 by rotating shaft 14.The two ends of rotating shaft 14 are connected with forces down spring 16.Connecting rod 29 is connected with between L-type limiting card, connecting rod 29 is connected with ox horn curved boom 26, the top of ox horn curved boom 26 is fixed with inertia ball 20, inertia ball 20 rear end is provided with U-shape lock part 18, the front end of U-shape lock part 18 is plugged with hold-down arm 8, hold-down arm is supported on below flap, and the rear end of U-shape lock part 18 is connected with lever 19, and the bottom of lever 19 is fixed on pad anvil 17.U-shape lock part is connected with retracing spring 21, retracing spring one end is connected on U-shape lock part, and the other end is connected to seat front end.
Single direction ratchet is stuck in the unidirectional slip of restriction seat in the poroid draw-in groove on slide rail, and L-type limiting card is stuck in the unidirectional slip of restriction seat in the dentation draw-in groove on slide rail.
Further, the front portion of slide mechanism is provided with postive stop baffle 23, and the rear portion of slide mechanism is provided with spacing mandril 15.Spacing mandril can cause flap to turn down with the effect of pad anvil indirectly.
The outside of seat is provided with the chair back adjusting yoke 3 of manual regulation angle of back-rest, and the car body at chair back adjusting yoke 3 rear is provided with extrude bar 4.
Whole seat is fixed on body bottom panel by footing 32, when collision happens accident, because effect of inertia makes inertia ball 20 and ox horn curved boom 26 around anchor shaft 25 tip forwards, ox horn curved boom 26 lower end can promote connecting rod 29 backward, and block connecting rod 29 by the gap of ox horn curved boom 26, make connecting rod can not self-return.Connecting rod 29 be pushed rearward dynamic while make L-type limiting card 30 around axle 33 overturning backward, make L-type limiting card depart from dentation draw-in groove 12, because single direction ratchet 11 can only rotate backward, so seat can not forward slip.When driver and crew are clashed into or extrude, seat can slide backward automatically as driver and crew provide larger space.This is first heavily to protect.
If seat is back to the limit, when the space provided is still not enough, pad anvil 17 can be subject to the pushing of spacing mandril 15, lever 19 is rotated around pole 13, U-shape lock part is pulled back, and latch 22 exits from spacing hole 6, and hold-down arm 8 pivot shaft 5 that can rotate under the effect of spring 7 rotates, flap turns over for 10 times, for the leg of driver and crew provides space.This is second heavily to protect.
Seat is back to while the limit, and extrude bar 4 can contact with chair back adjusting yoke 3 and upwardly chair back adjusting yoke 3, removes the lock function of the chair back, avoids chaufeur to be clamped by bearing circle and the chair back, also for save and escape provides space.This is triple protection.
Seat is in every day use, and the ratchet of single direction ratchet is connected in poroid draw-in groove 12, and the card article of L-type limiting card is connected in dentation draw-in groove, defines seat position.When needing the position of adjusting seat front and back, can upwards pull adjust bar 28, the postive stop baffle 23 be fixed on L-type limiting card is held up by adjust bar 28 side arm, and drive that L-type limiting card 30 leaves dentation draw-in groove, single direction ratchet 11 leaves poroid draw-in groove 12, gangbar 34 drives dividing plate 35 to rise and blocks pad anvil 17 simultaneously, avoids spacing mandril 15 to push up pad anvil 17 and causes misoperation and seat turnover occurs.The effect of stabilizing spring 24 increases the stability of inertia ball 20.Effect near spring 27 holds connecting rod 29 to make the limited locking of L-type limiting card, and when inertia ball 20 resets, pull connecting rod 29 by this near spring 27, L-type limiting card 30 resetted, is stuck in dentation draw-in groove 12.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this specification sheets; made all equivalently to substitute, obvious form of distortion, within the essential scope all dropping on this specification sheets, protection of the present utility model ought to be subject to.
