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.

    本发明提供了一种汽车座椅防潜装置,包括位于座椅软垫前部下方的杆长方向与车宽方向一致的防潜横杆,所述防潜横杆与驱动其由低位向高位复位的复位机构相连,高、低位限位机构分别将防潜横杆限位在高位和低位,高、低位限位机构上设置有碰撞时解除低位限位的解锁机构。上述方案中,正常行驶时防潜横杆位于低位,对汽车座椅软垫的干涉小,驾乘者不易通过软垫感受到防潜横杆,提高了乘坐舒适度,当发生碰撞时防潜横杆解除低位限位到达高位,保证乘坐人员的安全性。
