Abstract

The utility model discloses an automobile safety chair which comprises a back rest and a fixed cushion framework, wherein a movable cushion framework is arranged in the fixed cushion framework, a rotating shaft is connected between two lateral frames of the fixed cushion framework, one end of each of the two lateral frames of the movable cushion framework is hinged on the rotating shaft, and the other end of each of the two lateral frames of the movable cushion framework is connected with a lifting drive mechanism. Due to the adoption of the structure, the automobile safety chair provided by the utility model has the advantages as follows: 1, in case of collision of an automobile, an auto body controller controls the ejector rod of an action device to extend out, so as to enable the movable cushion framework to rise to lift the cushion, a passenger is enabled to keep a posture which is beneficial in front bumping, meanwhile, a trunk body is enabled to slip upward so as to consume a part of energy, and risks of mortal injury to a driver during front bumping can be reduced; and 2, a one-way self-locking groove on the ejector rod of the action device is prevented from being squashed when the passenger slips along the chair surface.

Description

A kind of safety chair seats of car

Technical field

The utility model relates to the automotive seat technical field, particularly a kind of safety chair seats of car.

Background technology

In the passive security field, the form of seat design and vehicle occupant protection performance have important relationship.In the central collision process; The anti-dive safety seat of common passive type safety can only occupant's trunk forward slippage effect of contraction just takes place later on; At this moment the effect of contraction that receives owing to the occupant is not prompt enough, and causes the chest acceleration/accel too high, and the powerful inertia effect damages the chest of chaufeur.At present; Disclosed Chinese patent has the preparatory backstroke safety seat (patent No.: CN201235764), the safety seat (patent No.: CN1930019), the anti-collision safety chair for automobile (patent No.: CN1843804), a kind of safety seat (patent No.: patent such as CN101691109A), but there is complex structure respectively in the seat technology in these patents, manufacturing cost is high, travelling comfort is bad and vehicle body is changed problems such as requiring height.

The utility model content

The utility model technical matters to be solved is to the deficiency of prior art, a kind of safety chair seats of car that when bumping, reduces effect of inertia to the injury of chaufeur chest to be provided.

For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of safety chair seats of car; Comprise back of seat, fixing cushion frame, be provided with the movable sitting cushion framework in the described fixedly cushion frame, be connected with rotating shaft between the both sides frame of described fixedly cushion frame; One end of the side frame of described movable sitting cushion framework is hinged in the rotating shaft, and the other end is connected with lift drive mechanism.

Described lift drive mechanism comprises actuator, rocking arm; Described rocking arm is " L " type connecting rod; Described actuator is connected fixedly on the cushion frame, and the push rod end of described actuator is connected with rocking arm one end, and the rocking arm other end is connected on the movable sitting cushion framework.

The push rod of described actuator is provided with the unidirectional self-lock groove.

Described actuator is electrically connected with car body controller.

The input end of described car body controller is connected with collision acceleration sensor.

Be provided with automobile cushion in the described movable sitting cushion framework.

The utility model adopts said structure; Have the following advantages: 1, when automobile bumps, car body controller control action device push rod stretches out, and makes the movable sitting cushion framework rise; Raise cushion; The posture of bumping before the occupant being maintained be beneficial to makes the trunk slippage that makes progress consume part energy simultaneously, and chaufeur receives the risk of mortal injury in bumping before reducing; 2, the unidirectional self-lock groove on the push rod of actuator can prevent the occupant during along the seat slippage with its conquassation.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation;

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

Fig. 2 is the logical organization block diagram of the signal control actuator that car body controller is gathered according to collision acceleration sensor in the utility model;

In Fig. 1～2,1, back of seat; 2, fixing cushion frame; 3, movable sitting cushion framework; 4, rotating shaft; 5, actuator; 6, rocking arm; 7, car body controller; 8, collision acceleration sensor.

The specific embodiment

Like Fig. 1～a kind of safety chair seats of car shown in Figure 2; Comprise back of seat 1, fixing cushion frame 2; Fixedly be provided with movable sitting cushion framework 3 in the cushion frame 2; Fixedly be connected with rotating shaft 4 between the both sides frame of cushion frame 2, an end of the side frame of movable sitting cushion framework 3 is hinged in the rotating shaft 4, and the other end is connected with lift drive mechanism.

Lift drive mechanism comprises actuator 5, rocking arm 6, and rocking arm 6 is " L " type connecting rod, and actuator 5 is connected fixedly on the cushion frame 2, and the push rod end of actuator 5 is connected with rocking arm 6 one ends, and rocking arm 6 other ends are connected on the movable sitting cushion framework.The push rod of actuator 5 is provided with the unidirectional self-lock groove.Actuator 5 is electrically connected with car body controller 7.The input end of car body controller 7 is connected with collision acceleration sensor 8.Be provided with automobile cushion in the movable sitting cushion framework 3.

Collision acceleration sensor 8 detects when bumping accident before vehicle takes place, and passes the signal to car body controller 7, and car body controller 7 is at 10 milliseconds of left and right sides trigger action devices; Actuator 5 push rods stretch out; Promote rocking arm 6, make the movable sitting cushion framework that is connected with rocking arm 6 rise, raise the cushion inclination angle; The posture of bumping before the occupant being maintained be beneficial to; Make the trunk slippage that makes progress consume part energy simultaneously, chaufeur receives the risk of mortal injury in bumping before reducing, and reduces the injury that chest is caused by the powerful inertia effect.Unidirectional self-lock groove on the push rod of actuator can prevent the occupant during along the seat slippage with its conquassation.

Under the prerequisite that does not influence original body drawing and travelling comfort, this technology is bumped the inertia loading that trunk bore in the process before can weakening greatly, effectively reduces the chest acceleration peak value, has guaranteed lower cost and system integration property preferably simultaneously.This utility model is better compatible, need not to change the seat slide mounting means, and applicable to forward and backward row's seat.

Occupant restraint efficient in bumping before this utility model effectively raises with lower cost and simple structure improves vehicle safety, all can be applied at vehicular drive seat, co-pilot seat and row occupant seat, other backs.

Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technical scheme is carried out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
