Anti-submarine device for car seat

Abstract

The invention provides an anti-submarine device for a car seat, which comprises an anti-submarine cross bar whose rod length direction is consistent with the vehicle width direction under the front part of the seat cushion, and the anti-submarine cross bar is driven from a low position to a high position. The resetting mechanism of reset links to each other, and the high and low position limit mechanisms respectively limit the anti-submarine cross bar in the high position and the low position, and the high and low position limit mechanisms are provided with the unlocking driving force that removes the low position limit when colliding. In the above scheme, the anti-submarine crossbar is at a low position during normal driving, and the interference with the car seat cushion is small, and it is difficult for the driver and passengers to feel the anti-submarine crossbar through the cushion, which improves the ride comfort and prevents submersion in the event of a collision. The cross bar is released from the low limit to the high position to ensure the safety of the passengers.

Description

technical field [0001] The invention belongs to the field of automobile seat frames, in particular to an anti-submersion device for automobile seats. Background technique [0002] In the car seat system, the seat cushion frame and foam will ensure the sitting posture when the driver is riding, but when braking or front collision occurs, in addition to the passive safety device of the seat belt, the seat also needs to provide sufficient support , the anti-submarine structure is thus produced. The utility model can support the lower half of the human body of the driver and occupant, give the component force in the backward and upward directions, and reduce the greater damage caused by the forward and downward sliding of the human body. The anti-submarine device is usually designed to have a higher front end and a lower rear end of the sheet parts under the seat cushion to prevent the body or pelvis of the occupants from sliding forward from the seat belt when the vehicle is h...

AI Technical Summary

Problems solved by technology

In order to ensure a good anti-dive effect, the height of the cross tube is generally higher, so that the human body will clearly feel the cross tube under the legs, and the pressure between the legs and the cross tube will be obvious after a long ride. feeling uncomfortable
