Anti-submersion car seat with multi-level control

Abstract

The invention relates to an anti-submersion car seat with multi-level control, which includes a seat back, a seat pan frame, a seat cushion arranged on the seat pan frame, and an anti-submergence mechanism. Submersion units, each of the anti-submersion units includes a first connector group and a second connector group respectively arranged on both sides of the seat pan frame, located under the seat cushion and passing through the first connector at intervals The connecting ropes of each connecting piece of the group and the second connecting piece set are arranged on one of the two sides of the seat pan frame for winding or releasing the winding mechanism of the connecting rope, the One end of the connecting rope is connected to one of the two sides of the seat pan frame, and the other end is connected to the winding mechanism. The anti-submersion mechanism of the automobile seat of the present invention adjusts the rope of the connecting rope through the winding mechanism to control the stiffness of the seat cushion, has a simple structure, flexible layout, small additional mass, and does not affect the comfort of the seat during normal riding.

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, reinforcement 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
