Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a seat anti-submersion mechanism and seat. Background Technology

[0002] With the increasing popularity of automobiles and the rising demands for their functionality, the safety, comfort, and practicality of vehicles are receiving more and more attention. In the event of a frontal collision, passengers are prone to being thrown forward, potentially resulting in serious injury. Given the ever-increasing safety requirements, incorporating fixed anti-throwing structures into the car seat frame can provide a certain degree of protection against this phenomenon.

[0003] However, there is a contradiction between the anti-submarine performance and the riding comfort of existing seats. They are effective at preventing submarine descent but have poor riding comfort, or they are ineffective at preventing submarine descent but have good riding comfort.

[0004] Therefore, it is necessary to design a seat anti-submersion mechanism and a seat to improve the above problems. Utility Model Content

[0007] A seat anti-submersion mechanism includes an ignition mechanism, an anti-submersion bracket connected to the ignition mechanism, and an anti-submersion steel wire connected to the anti-submersion bracket. The anti-submersion bracket is symmetrically arranged on both sides of the front cross tube of the seat. The anti-submersion steel wire is provided with multiple protrusions. After the ignition mechanism pulls the anti-submersion bracket to rotate, the protrusions of the anti-submersion steel wire are lifted.

[0008] As a preferred embodiment of this invention, the detonation mechanism includes a pull rod, which is connected to the anti-submersion bracket.

[0009] As a preferred embodiment of this utility model, the anti-submersion bracket is welded and fixed to the front horizontal tube of the seat.

[0010] As a preferred embodiment of this invention, both ends of the anti-submersion steel wire are fixedly connected to the anti-submersion bracket.

[0011] As a preferred embodiment of this invention, the raised portion is lifted to a height greater than 15mm.

[0012] As a preferred embodiment of this invention, the diameter of the anti-submersion steel wire is not less than 5mm.

[0013] As a preferred embodiment of this utility model, the front cross tube of the seat is rotatably connected to the side plate of the seat cushion.

[0014] Another objective of this utility model is to provide a seat equipped with the seat anti-submersion mechanism described above.

[0015] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are:

[0016] 1. The present invention relates to a seat anti-submersion mechanism and seat, which adopts a mechanical structure, has a simple structure, short trigger time, stable anti-submersion effect, and can improve the safety of car seats during car collisions, and has good practicality.

[0017] 2. The present invention relates to a seat anti-submersion mechanism and seat, wherein when the detonation mechanism is not triggered, the anti-submersion steel wire is in a retracted state, reducing the hard object feeling when the passenger sits and improving the riding comfort.

[0030] The following will refer to Figures 1 to 4 The working principle of this utility model will be explained.

[0031] When a vehicle collision occurs, the detonation mechanism 1 is triggered and pulls the lever 11, which in turn pulls the anti-submarine support 2 connected to the lever 11 to rotate. The front cross tube of the seat 4 rotates by relying on the side panel of the seat cushion, which drives the anti-submarine support 2 on the other side to rotate. The anti-submarine wire 3 rotates synchronously with the anti-submarine support 2 and the front cross tube of the seat 4. The protrusion 31 of the anti-submarine wire 3 is raised. The protrusion 31 moves upward through the corresponding hole in the seat basin to prevent the occupant from submerging, thus playing an anti-submarine role.
