Embodiment Construction

[0013] An anti-submarine device for a car seat, comprising an anti-submarine cross bar 10 whose rod length direction is consistent with the vehicle width direction under the front part of the seat cushion, and is characterized in that: the anti-submarine cross bar 10 is driven by a low position Link to each other to the resetting mechanism of high position reset, high and low position limit mechanism respectively with anti-submarine cross bar 10 limit in high position and low position, high and low position limit mechanism are provided with the unlocking mechanism that removes low position limit when bumping.

[0014] In the above-mentioned scheme, after the automobile leaves the factory, the anti-submarine crossbar 10 is placed in a low position, and its position is limited by a limit mechanism. The passenger's legs improve the comfort of the driver and passenger. Since a slight collision has a low dive effect on the driver and passenger, the threat to the safety of the driver...

Abstract

The invention provides an automobile seat anti-diving device. The device comprises an anti-diving cross rod which is located below the front portion of a seat cushion, the rod length direction of theanti-diving cross rod is consistent with the vehicle width direction, the anti-diving cross rod is connected with a reset mechanism driving the anti-diving cross rod to reset from a low position to ahigh position, a high-position and low-position limiting mechanism limits the anti-diving cross rod at the high position and the low position respectively, and the high-position and low-position limiting mechanism is provided with an unlocking mechanism for relieving low-position limiting during collision. During normal driving, the anti-diving cross rod is located at the low position, interference to the automobile seat cushion is small, a driver and passengers do not easily feel the anti-diving cross rod through the cushion, and the riding comfort degree is improved; and when collision occurs, the anti-diving cross rod relieves low-position limitation to reach the high position, and the safety of the passengers is guaranteed.

Description

technical field [0001] The invention belongs to the field of car seat frames, in particular to an anti-submersion device for car seats. Background technique [0002] In the car seat system, when the driver and the occupant are riding, the cushion frame and foam will ensure the sitting posture, but when braking or frontal 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. It 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 human body sliding forward and downward. The anti-submarine device usually designs the sheet metal under the seat cushion with a higher front end and a lower rear end to prevent the occupant's body or pelvis from sliding forward from under the seat belt when the vehicle encounters a frontal collision or ...
