Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to an automotive seat structure for emergency escape when a vehicle is wading through water. Background Technology

[0002] When a vehicle is submerged in water due to extreme weather or improper driver operation, it may experience a short circuit in the vehicle's electrical system, or water pressure may prevent the doors from opening or the power windows from malfunctioning, potentially trapping passengers inside. Traditional seating structures cannot provide rapid escape support, therefore a seating structure integrating escape assistance functions needs to be designed. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a car seat structure for emergency escape when a vehicle is wading through water. The car seat structure integrates escape aids, which can promptly remind passengers when the vehicle is wading through water. The hidden inflatable airbag can form a life ring after deployment, which is conducive to getting out of trouble. The window hammers integrated on both sides of the airbag make it easy for people in the vehicle to break the window and escape, ensuring that the vehicle can escape in an emergency when it is wading through water.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A car seat structure for emergency escape when a vehicle is wading through water includes a seat body, the seat body including a backrest and a seat cushion, the seat cushion including a seat cushion frame, seat cushion foam, and seat cushion cover. The improvement is that a water pressure sensor is installed at the bottom of the seat cushion frame, the water pressure sensor being electrically connected to the vehicle's central controller; an embedded groove is machined into the inner side of the seat foam, exposing the seat cushion frame at the embedded groove; an inflatable rescue module is installed at the embedded groove; the inflatable rescue module includes an airbag. The system includes a base, an inflatable airbag, and a decorative cover. The airbag mounting base is fixed to the seat cushion frame. When the inflatable airbag is unfolded, it forms a life ring structure. The airbag contains a gas generator, and its inner ring has ears that secure the folded airbag to the mounting base and embed it into the recessed groove. The seat cushion cover has an airbag burst opening at a position opposite to the inflatable life-saving module. The decorative cover is located at the airbag burst opening and is used to cover the inflatable airbag within the recessed groove.

[0006] As a preferred embodiment of this invention, the inflatable airbag is further provided with window-breaking hammers on both sides.

[0007] As a preferred embodiment of this invention, the gas generator is electrically connected to a central controller, and the igniter inside the gas generator is ignited by the central controller.

[0008] As a preferred embodiment of this invention, the airbag mounting base is fixed to the seat cushion frame by screws, and the inflatable airbag has mounting holes on its lugs and is fixed to the airbag mounting base by Christmas tree nails.

[0009] As a preferred embodiment of this utility model, the decorative cover is shaped to resemble the airbag rupture opening, is installed at the airbag rupture opening by an interference fit, and its end is connected to the seat cushion cover by a flexible connection structure.

[0010] Advantages and beneficial effects of this utility model:

[0011] (1) The car seat structure provided by this utility model integrates an escape aid device, which can promptly remind passengers when the vehicle is in water. The hidden inflatable airbag can form a life ring after it is deployed, which is conducive to getting out of trouble. The window hammers integrated on both sides of the airbag facilitate the escape of people in the vehicle by breaking the window, ensuring that the vehicle can escape in an emergency when it is in water.

[0012] (2) The car seat structure provided by this utility model has a water pressure sensor set at the bottom of the seat cushion frame and an inflatable life-saving module set in the embedded groove of the seat cushion foam. The water pressure sensor and the inflatable life-saving module form a height difference. This design can ensure that after the water pressure sensor detects the water wading signal, the vehicle's central controller can smoothly pop out the inflatable airbag to form a life ring, which is convenient for underwater escape.

[0013] (3) The car seat structure provided by this utility model has a decorative cover at the airbag bursting port to ensure the overall aesthetics of the seat and not affect the airbag popping out. Moreover, the end of the decorative cover is connected to the seat cushion cover through a soft connection structure. This design can avoid the safety hazard of the decorative cover being blown away.

[0014] (4) The inflatable airbag of this utility model is fixed on the airbag mounting base by Christmas tree nails. It is easy to install, and because its fastening strength is not high, it is easy to remove the inflatable airbag from the seat and use it as a life ring. Attached Figure Description
