Abstract

The utility model relates to an automotive safety seat. The utility model comprises a seat cushion and a back cushion, wherein, a spring which drives the back cushion to be backwards rotated and opened is arranged between the seat cushion and the back cushion; a cylinder component which drives the back cushion to be rotated forwards and backwards is arranged between the seat cushion and the back cushion. Under the action of the elastic force of the compression spring, the back cushion always has the action of the force which backwards rotates for avoiding that a drive and a passenger violently impact an object or an air sac in an automobile because of inertia when an automobile crash accident happens.

Description

Safety chair seats of car

Technical field

The utility model discloses a kind of seat, specifically is a kind of seat that is suitable for installing on the automobile.

Background technology

In the prior art, in order to ensure automobile driver and crew's safety, driver and crew's safety when especially guaranteeing that by the mode that adds safety air bag automobile crashes.Because the instantaneous impact of airbag opening is very huge, in case accident takes place, the occupant will be subjected to the bump from air bag and Che Nei object, and driver and crew are come to harm.

Technology contents

The purpose of this utility model provides a kind of safety chair seats of car, and when collision case took place, the direction motion opposite with inertia motion took place seat, thus the collision that slows down object in driver and crew and air bag or the car.

For achieving the above object, the technical solution adopted in the utility model is: safety chair seats of car, it comprises seat cushion and back cushion, it is characterized in that: be provided with between seat cushion and the back cushion and order about the spring that back cushion rotates backward and opens, be provided with between seat cushion and the back cushion and order about the cylinder assembly of back cushion to forward and backward rotation.

As shown from the above technical solution, under the elastic force effect of compression spring, the power effect that back cushion is rotated backward all the time, personnel will rotate backward together in company with back cushion under the constraint of safety strap, avoided driver and crew when car accident takes place since inertia and with car in object or air bag clash, for the effect of above-mentioned spring when accident takes place is brought into play, have the piston rod action of control setup and senser element control cylinder to echo mutually with the effect of compression spring, i.e. the action of piston rod also is that back cushion is opened.

Summary of drawings

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

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 is a lateral plan of the present utility model.

The specific embodiment

As shown in Figure 1, safety chair seats of car comprises seat cushion 10 and back cushion 20, is provided with between seat cushion 10 and the back cushion 20 to order about the spring 50 that back cushion 20 rotates backward and opens, and is provided with between seat cushion 10 and the back cushion 20 and orders about the cylinder assembly of back cushion 20 to forward and backward rotation.Because the elastic force of spring 50 is bigger, and the action direction of its elastic force orders about back cushion 20 and rearward opens rotation, for the ease of back cushion 20 is forwards rotated adjustment, be provided with cylinder 30, seat cushion 10 is provided with fixed support 40, be provided with on cylinder body one end of the cylinder 30 that the approximate horizontal shape is arranged and the described fixed support 40 with the vertical pivot shaft 41 of automobile working direction on hinged cooperation of formation, the support 21 that is connected on the end of the piston rod 31 of cylinder 30 and the back cushion 20 is hinged, and be positioned at the top of the hinged rotating shaft 60 of seat cushion 10 and back cushion 20, described spring 50 is two stage clips and the both sides that are arranged in cylinder 30, simultaneously the end referring to Fig. 2 spring 50 is fixed on the pivot shaft 41, and the other end links to each other with support 23 on the back cushion 20 and connecting place is higher than the end and support 21 hinge point of piston rod 31.

As seen from Figure 3, the following side of described back cushion 20 is provided with the cylinder 90 that the approximate vertical direction is arranged, the end of the piston rod 91 on being positioned at is hinged with the rod member 110 that is fixed on the back cushion 20, the spring 100 that is set on the piston rod 91 is arranged between the cylinder body of cylinder 90 and the rod member 110, and this spring 100 is a stage clip.

Be provided with the cylinder 80 that general horizontal direction is arranged between back cushion 20 and the car body, concrete captive joint mode can be referring to Fig. 3, cylinder body one end that is cylinder 80 is hinged with the support 70 that is fixed on the car body, and the support 11 that the end of piston rod and seat cushion 10 bottoms are provided with is hinged.

The position that respectively is articulated and connected in the foregoing description is in order to satisfy the needs of each parts rotation displacement.

The concrete action of cylinder 30,80,90 is controlled by comprehensive valve body in the utility model, and the break-make control of each valve body belongs to prior art, repeats no more herein.
