Abstract

The utility model relates to a rocking-able passengers' seat for vehicles, which is characterized in that both sides of a seat 1 are provided with supporting ears 2; a backrest 3 is connected with the supporting ears 2 by a shaft 6 and nuts 7; both sides of the backrest 3 are fixed with pins 5 which are penetrated in slide grooves of the supporting ears 2; a torsion spring 8 is sheathed on the shaft 6; both ends of the torsion spring 8 are respectively fixed on a base seat 1 and the backrest 3. An installing belt 4 is installed on the position on the backrest 3 adjacent to breasts of passengers. The product makes passengers' bodies together with the backrests do rocking buffering movement within definite range at collision moment and finally rest on the initial sitting position. Consequently, the impact force and the damage born by the passengers because of the collision are obviously lightened.

Description

Swingable automotive seat

The utility model relates to the seat on a kind of automobile, particularly a kind of swingable automotive seat.

The simplest automotive seat have pedestal at present, backrest etc., and its pedestal and backrest are fixed together, if run in the driving when colliding, the human body natural can collide with article on every side, and is very dangerous.Add on the backrest of aforesaid automotive seat load onto safety strap after, if safety strap is connected together from belly and backrest, when then colliding, occupant's upper body, particularly head movement distance are bigger than normal, easily bump forward seat or other article, do not have protective effect.When the occupant used of seat belts in by bus, human body was subjected to the constraint of safety strap, and human body reduces with article possibility of collision on every side, but because backrest can not rotate, does not have and wave kicking motion, and it is bigger than normal still to make human body be subjected to impulsive force, and head, neck are easily injured.Other has a kind of automotive seat that generally use, and its backrest can be fixed with safety strap around a rotation by recliner on the seat, but after mixing up angle, if run into when colliding, backrest but can not rotate, and does not have and waves kicking motion, still safety inadequately.

The purpose of this utility model is a kind of swingable automotive seat of developing at above problem, this structure can make the occupant when colliding, health and backrest are done within the specific limits together and are waved kicking motion, be still at last on the position of initially taking, thereby obviously alleviate impulsive force and the injury that the occupant is subjected to because of collision.

The utility model is achieved in that swingable automotive seat, comprise pedestal 1, backrest 3 and safety strap 4, wherein, in the both sides of pedestal 1 journal stirrup 2 is arranged, backrest 3 is by axle 6 and nut 7 and journal stirrup 2 bonded assemblys, the both sides of backrest 3 are fixed with pin 5, pin 5 is installed in the chute of journal stirrup 2, is set with torsion spring 8 on axle 6, and the two ends of torsion spring 8 are separately fixed on pedestal 1 and the backrest 3.

The utility model can also be achieved in that safety strap 4 is contained on the position near occupant's chest on the backrest 3.

Good effect of the present utility model is:

1, this structure has in the moment of colliding and can wave, and is safe in utilization, characteristic of simple structure.

2, this product can make the occupant in the moment of colliding, and health and backrest wave together, is still at last initially to take the position, thereby obviously alleviates impulsive force and the injury that when colliding the occupant is caused.

Description of drawings.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A of Fig. 1---the A cutaway view.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, 2, the pedestal 1 of swingable automotive seat can be fixed together with car chassis, in the both sides of pedestal 1 journal stirrup 2 is arranged, and backrest 3 links together with journal stirrup 2 by axle 6 and nut 7, and backrest 3 can rotate around axle 6.The both sides of backrest 3 are fixed with pin 5, and pin 5 passes respectively in the chute of journal stirrup 2, is subjected to the restriction of chute, and backrest 3 can only rotate in certain angle around axle 6.Torsion spring 8 is sleeved on the axle 6, and the two ends of torsion spring 8 are separately fixed on pedestal 1 and the backrest 3.By the initial torsion of torsion spring 8, backrest 3 is pressed in last position, promptly initially take the position.When backrest 3 goes to anteposition, the torsion maximum of torsion spring 8.Safety strap 4 is contained on the position near occupant's chest on the backrest 3.When the occupant rides, connect together from the front health and backrest 3 with safety strap 4, safety strap 4 has farthest limited the action radius of occupant's health when colliding, thereby has played protective effect, so the safety strap 4 of this structure has characteristics safe in utilization.If run into collision in the driving, but when not overturning, because action of inertia, human body and backrest 3 generally can rotate counterclockwise an angle, when pin 5 slided into the anteposition of the chute on the journal stirrup 2, backrest 3 just can not rotate counterclockwise again, at this moment the torsion maximum of torsion spring 8, be subjected to the effect of torsion spring power and chute, backrest 3 clockwise rotates again; When the last position of the chute on pin 5 and the journal stirrup 2 contacted, backrest 3 stopped to clockwise rotate; At this moment because last of the chute on pin 5 and the journal stirrup 2 collides, so backrest 3 can rotate counterclockwise again; Backrest 3 will repeat above motion process later on, and promptly backrest 3 is done oscillating motion, up to the effect because of torsion spring power, resistance, and make backrest 3 be still in last position.Because this oscillating motion makes health be subjected to repeatedly cushioning, thereby alleviates maximum impact force significantly, makes health be difficult for coming to harm.
