AI Technical Summary
Existing strip-shaped airbag mattresses are prone to significant deformation when inflated, resulting in poor support and noise caused by friction between the side walls of adjacent airbags, which affects the user experience.
A sheet-like brace is installed in the middle of the bladder. The periphery of the brace is continuously adhered to the side wall of the bladder to limit the deformation of the middle of the bladder. The upper and lower chambers are connected through a through hole to achieve synchronous air pressure regulation and reduce contact between adjacent bladders.
It effectively prevents the expansion and deformation of the middle part of the bladder, improves vertical support performance, eliminates noise, and enhances the user experience.

Abstract
Claims
1. A strip-shaped airbag having good resistance to deformation, comprising a bag body (1) in the form of a long strip, characterized in that, The capsule (1) is provided with sheet-like reinforcing bars (2). The reinforcing bars (2) are horizontally arranged and their periphery is continuously bonded to the side wall of the capsule (1) to form an annular adhesive seam, so as to limit the deformation of the capsule (1) under stress.
2. A strip airbag according to claim 1, wherein The bladder (1) is divided into an upper cavity (7) and a lower cavity (8) by a reinforcing bar (2). The reinforcing bar (2) is provided with a through hole (12) so that the upper cavity (7) and the lower cavity (8) can be connected through the through hole (12).
3. A strip airbag according to claim 2, wherein The bottom end face of the capsule (1) is provided with an air nozzle (9) that communicates with the outside. The upper cavity (7) is connected to the air nozzle (9) through a through hole (12) so that the air pressure in the upper cavity (7) and the lower cavity (8) can be synchronously adjusted through the air nozzle (9).
4. A strip airbag according to claim 3, wherein The through holes are multiple and distributed in a matrix on the tie rod (2).
5. A strip airbag according to any one of claims 2 to 4, characterised in that, The capsule (1) includes an end face sheet (3) and an annular rim sheet (4). The end face sheet (3) covers the upper and lower ports of the rim sheet (4) so that the end face sheet (3) and the rim sheet (4) are bonded together to form the capsule (1).
6. A strip airbag according to claim 5, wherein The edge sheet (4) includes two parallel linear segments (5) and an arc segment (6) spanning the corresponding ends of the linear segments (5). The linear segments (5) and the arc segment (6) are alternately bonded to the periphery of the tie rod (2) to form the annular adhesive seam.
7. A strip airbag according to claim 5, wherein The tie rod (2) is continuously bonded horizontally along the centerline of the edge sheet (4) so that the upper cavity (7) and the lower cavity (8) have the same height.
8. A strip airbag according to claim 5, wherein The edge sheet (4) is formed by bonding at least one long strip substrate together at the ends.
9. The strip airbag of claim 5, wherein Both the end face sheet (3) and the surrounding sheet (4) are made of multi-layered materials.
10. A mattress comprising a support layer (10) and an outer cover (11) enveloping the support layer (10), characterized in that, The support layer (10) is provided with a strip-shaped airbag as described in any one of claims 1-9, the strip-shaped airbags are arranged side by side and joined together on the top surface to form a flat support surface.
