Problems solved by technology

[0008] However, in order to achieve a certain supporting effect, the above-mentioned multiple inserts or protrusion structures need to have a certain hardness, which will reduce the comfort
Moreover, the protrusion structure with uneven thickness will also increase the thickness of the shoulder pad and reduce the comfort

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Disclosed by the present invention is a safety belt shoulder pad, such as Figure 1 to Figure 4 Shown is the first preferred embodiment of the present invention. The shoulder pad 1 can be movably arranged on the shoulder belt 2 of the safety belt through the shoulder belt perforation 11 thereon, and can also be a part of the safety belt. The key of the present invention is that the main body of the shoulder pad 1 is made of soft material, such as rubber or cloth. The interior of the main body is provided with an upper chamber 12 and a lower chamber 13 which communicate with each other, and fluids such as gas are sealed in the upper and lower chambers. The shoulder pad 1 is also provided with a telescopic structure to reset the inner wall of the lower chamber 13 (the side that is in contact with the user). The outer surface o...

Abstract

The invention discloses a safety belt shoulder pad which is made of a soft material. An upper cavity and a lower cavity which are communicated mutually are formed in a main body of the safety belt shoulder pad, and gas and other fluids are closed in the upper cavity and the lower cavity. The shoulder pad is also provided with an extensible structure. When the shoulder pad is in a normal unextruded state, the outer surfaces of the inner side walls of the upper cavity and the lower cavity are flush; when the upper portion of the shoulder pad is extruded, the fluid in the upper cavity flows and extrudes the lower cavity, and the resistance of the extensible structure is overcome to make the inner side wall of the lower cavity propped open in an arc-shaped mode so as to make the lower cavity of a big end down structure. When a vehicle is collided in the using process of a child safety seat, the shoulder pad structure can be better close to the change of the chest movement response of the child passenger body and play the continuous contact protection effect on the child passenger. Accordingly, the displacement bending angle of the child can be better limited, and the taking safety of the child is improved.

Description

technical field [0001] The invention relates to a safety belt shoulder pad, which is used for the shoulder pad on the five-point safety belt of a car seat, especially a child safety seat. The shoulder pad can be a part of the five-point safety belt or a safety belt. An accessory to bring. Background technique [0002] Car seat belts are indispensable accessories in cars. In order to increase the cushioning performance and comfort of the seat belts, shoulder pads are often installed on the seat belts to increase the thickness of the shoulders and chest of the seat belts. Some safety belts are directly provided with air cushions or inflatable chambers, which achieve the purpose of cushioning and comfort through the cushioning effect of the gas. For example: CN200610145595.5 discloses a "special inflatable safety belt for automobiles", CN201010246937.9 discloses a "four-point inflatable comfortable safety belt for automobiles", and CN201180038756.X discloses a "safety belt for...
