Headrest fireproof system for transportation tool

Abstract

The invention discloses a headrest fire prevention system for a transportation tool. The headrest fire prevention system comprises a headrest body (100), a fire prevention suit (200), a release mechanism (300) and a connecting assembly (400). A fireproof suit storage unit (110) is arranged in the headrest body and supports single-mode, dual-mode or multi-mode compression storage, the compression ratio of a fireproof suit is larger than or equal to 8: 1, and the flame retardant property of the fireproof suit meets the BS EN 469: 2020 standard. The releasing mechanism is purely mechanically and manually triggered, and external energy input is not needed; the headrest can be customized to be of a special-shaped structure matched with the child safety seat, and the surface profile of the headrest comprises a cartoon shape or a polygonal geometry. The problems that a traditional fireproof device depends on external energy and is large in storage size and poor in adaptability are solved, and the device is particularly suitable for fire emergency protection of scenes such as new energy automobiles and high-speed rails.

Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle safety equipment, and particularly relates to a headrest fire protection system for transportation tools, especially applicable to fire emergency protection of transportation tools such as automobiles, high-speed rails, and airplanes. Background Art

[0002] The existing vehicle-mounted fire protection devices generally have the following problems: ‌Dependence on external energy‌: Most fire protection systems require electric power to drive the release mechanism and cannot be triggered when the vehicle loses power. ‌Limited storage space‌: The compression ratio of the fireproof suit is low (compression ratio < 5:1), resulting in an overly large volume of the storage unit. ‌Poor adaptability‌: The traditional headrest has a single structure and cannot adapt to the needs of child seats or special vehicle models. ‌Low wearing efficiency‌: It is difficult for the fireproof suit to quickly cover the key areas of the head and torso after being unfolded. The purpose of the present invention is to provide a headrest fire protection system that can be manually triggered, has no dependence on external energy, has a high compression ratio, and is adaptable to multiple scenarios. Summary of the Invention

[0003] Core Solution A headrest fire protection system for transportation tools, characterized by comprising: ‌Headrest body (100)‌: It is internally provided with a fireproof suit storage unit (110), supporting single-mode / double-mode / multi-mode storage structures, and the compression ratio of the fireproof suit (200) ≥ 8:1. ‌Release mechanism (300)‌: Purely mechanical and manually triggered, without external energy input, operated through a pull ring or a button. ‌Connection component (400)‌: The headrest and the seat are detachably fixed by using snap fasteners, slide rails or magnetic snap locks. ‌Adaptability design‌: The headrest body can be customized into a special-shaped structure (non-U-shaped / semi-circular) dedicated to child safety seats, the surface contour includes cartoon shapes or polyhedral geometries, and the filler is flame-retardant sponge or phase change material.

[0004] Technical Details ‌Fireproof suit (200)‌: The thickness is 0.2 - 1.5 mm, preferably an aramid fiber + ceramic coating fabric composite structure, meeting the fire retardant requirements of BSEN 469:2020 standard. ‌Combination method‌: The fireproof suit and the headrest are coupled by means of embedding, magnetic snap locks or slide rail slots. ‌Layered design‌: The fireproof suit fabric is a double-layer (fire retardant layer + heat insulation layer) or multi-layer composite structure, and the oxygen index of the outer fire retardant fabric ≥ 30. ‌Wearing form‌: Supports various styles such as pullover style, split style (top and pants are detachable), etc., suitable for adults, children and babies.

DETAILED DESCRIPTION

[0006] Example 1 (Standard headrest for automobile) The outer layer of the headrest body (100) is made of flame-retardant fabric (oxygen index ≥ 32) and filled with flame-retardant sponge; The fireproof clothing (200) is compressed and stored in a single-mode storage unit (110) in a cross-folded manner, with a compression ratio of 10:1; The release mechanism (300) is a spring-triggered pull ring, and after being pulled, the fireproof suit unfolds within 0.5 seconds to cover the head and torso; The connecting component (400) is a slide rail slot adapted to an ISO 13216 standard anchor point interface.

[0007] Example 2 (Headrest for child safety seat) The headrest body (100) is shaped like a panda, with a rounded surface contour and no sharp corners; The storage unit (110) adopts multi-mode block compression, and the fireproof clothing is designed as a split type (the top + pants are connected by snaps); The release mechanism (300) is integrated into the side of the headrest, and after the button is pressed, the fireproof suit falls naturally due to gravity.
