Problems solved by technology

This mechanism makes the back of the seat rotate to catch the head of the occupant who is thrown backward, and then rotates backward to absorb energy and improve the energy absorption effect of the headrest. However, the impact force of rear-end collision is still relatively large. , the back of the head will still be subject to a sudden impact, without weakening the sudden force on the neck in the longitudinal direction

Embodiment 1

[0024] Such as figure 1 As shown, the car seat is arranged on the car floor and includes a seat cushion 1. A cross link mechanism for up and down movement of the seat cushion 1 is arranged between the seat cushion 1 and the car floor. The cross link mechanism includes a hinge The straight bar one is 2 and the straight bar two is 3. The floor has a linear slide rail 4 arranged along the front and rear direction of the car, and one end of the two straight rods 3 can slide along the linear slide rail 4.

[0025] Specifically, one end of the straight rod 2 is hinged to the rear end of the chair cushion 1, and the other end is hinged to the floor. One end of the second straight rod 3 is hinged to the front end of the seat cushion 1, and the other end is embedded in the linear slide rail 4 and can move along the linear slide rail 4. A strip groove 5 is opened in the middle of the straight rod one 2, and a connecting shaft 6 is fixedly connected to the straight rod two 3 and is hinged ...

Embodiment 2

[0030] Such as figure 2 As shown, the main difference lies in the cross-link mechanism. One end of the straight rod 2 of this embodiment is hinged to the rear end of the chair cushion 1, and the other end is hinged to the floor. The lower end surface of the seat cushion 1 has a sliding groove 7 arranged along the front and rear direction of the car. One end of the second straight rod 3 is embedded in the sliding groove 7 and can slide along the sliding groove 7, and the other end of the second straight rod 3 is embedded in the linear sliding rail 4 The inner part can move along the linear slide 4, the lower end of the straight rod 2 can move back and forth along the linear slide 4, and the upper end can also slide back and forth along the slide groove 7 of the seat cushion 1. The upper end of the straight rod 2 is hinged on the rear end of the seat cushion 1, and the lower end is hinged on the car floor. The straight rod 1 2 and the straight rod 2 3 are clamped close to each ...

Abstract

The invention provides an automobile seat and a protecting device with the same and belongs to the technical field of automobile safety. The automobile seat solves the problem that an existing automobile seat enables a seat back to rotate to receive the head of a thrown-backwards passenger and then rotate backwards to absorb energy to improve energy absorption effect of a head pillow, but rear-end crash force is still large. The automobile seat is arranged on an automobile floor and comprises a seat cushion. A cross connecting rod mechanism which can drive the seat cushion to move up and down is arranged between the seat cushion and the automobile floor, and a power supply which can drive the cross connecting rod mechanism to move is further fixed on the automobile floor. By means of the cross connecting rod mechanism, the automobile seat is longitudinally stressed by impact of automobile bodies, and the head of the passenger is prevented from suddenly raising backwards and can move upwards or obliquely and upwards. Thus, the longitudinal sudden stress on the neck is weakened, the head raising-backwards range of the head of the passenger is reduced, an effect of relieving impact on the neck is achieved, and throwing harm to the neck is avoided.

Description

Technical field [0001] The invention belongs to the technical field of automobile safety, and relates to an automobile seat and a protective device with the seat. Background technique [0002] Survey data shows that more than 30% of drivers in rear-end collisions report neck injuries. When the car is rear-end collision, it will accelerate forward. Because of the large longitudinal impulse generated at the moment the body is hit, this force is transmitted to the contact part of the occupant and the seat, causing it to move forward, while the seat presses and pushes the torso of the occupant Moving forward, the head is lagging due to inertia. This lag will continue until the neck is stretched to the limit. The neck of the occupant is displaced backwards because it does not touch the seat, and the head is moved by the neck like a whiplash. Speed ​​up and throw forward. At this time, if the height of the seat headrest is inappropriate or the strength is not enough, the force transm...
