Multilevel control anti-dive automobile seat

Abstract

The invention relates to a multilevel control anti-dive automobile seat. The multilevel control anti-dive automobile seat comprises a seat back, a seat basin framework, a cushion arranged on the seat basin framework, and an anti-dive mechanism, wherein the anti-dive mechanism comprises multiple anti-dive units. Each anti-dive unit comprises a first connection piece assembly and a second connection piece assembly arranged on the two sides of the seat basin framework respectively, a connection rope which is located under the cushion and penetrates each connection piece of the first connection piece assembly and the second connection piece assembly at intervals, and a winding mechanism which is arranged on one side of the two sides of the seat basin framework and used for winding or releasing the connection rope; one end of the connection rope is connected with one side of the two sides of the seat basin framework, and the other end is connected with the winding mechanism. According to the anti-dive mechanism of the multilevel control anti-dive automobile seat, the rigidity of the cushion is controlled by the connection rope stretching regulation through the winding mechanisms; the structure is simple, the arrangement is flexible, the added mass is small, and the seat comfortableness during a normal ride is not influenced.

Description

technical field [0001] The invention belongs to the field of automobile safety occupant protection, is mainly used in industries such as automobiles, and in particular relates to a multi-stage control anti-submersion automobile seat. Background technique [0002] When the car has a frontal collision, the occupant will move forward under the action of inertia, and under the action of restraint systems such as seat belts, the occupant will also move downward to compress the seat cushion. This movement has an adverse effect on occupant protection - causing the belly strap of the seat belt to move upward relative to the hip, and in the worst case, causing the belly strap to slide over the front structure of the hip bone and invade the soft tissue of the abdomen, which is harmful to the occupant. The occupant suffers serious injuries, which are often referred to as "dive injuries". [0003] The measures in the existing technology to prevent the occupant from diving are mainly to...

AI Technical Summary

Problems solved by technology

However, this design still cannot provide sufficient rigidity at the middle and rear position of the seat; Chinese patent literature (announcement date: 2011.07.06, announcement number: CN 201890166U) discloses an anti-submersion mechanism, which consists of a car seat Cushion frame, reinforcing rods and steel wires used to form the seat basin

This mechanism raises the reinforcing bar at the front of the seat together with the seat pan steel wire to increase the support for the occupant's hip in the longitudinal direction, but the improvement is limited

In addition, this design requires a strong actuating device to realize the lifting of the reinforcing bar and the steel wire of the seat pan, thus increasing the quality of the seat, which is not conducive to the lightweight of the vehicle
