Problems solved by technology

Since the material used for the interior ceiling has good toughness and hardness, it is difficult for the interior ceiling to fall off from the joint of the B-pillar and C-pillar trim panels during the side air curtain blasting test, resulting in the side air curtain being damaged by the B-pillar and C-pillar. The interior trim panel is hung, so that the side air curtain cannot be released to the designated position in the event of a collision accident and loses its effect

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with embodiment.

[0018] During specific implementation: if Figure 1 ~ Figure 3 As shown, a weakening structure for auxiliary safety air curtain deployment on the roof of an automobile, both sides in the width direction of the interior decoration ceiling 1 have weakening grooves 2 arranged along its length direction, and it is characterized in that the weakening groove 2 has Notches arranged along the length direction of the weakening groove 2 are arranged at equidistant intervals along the length direction of the weakening groove 2 .

[0019] Since the material used for the interior ceiling has good toughness and hardness, setting a cut on the weakened groove can reduce the toughness and strength of the weakened groove, so that the safety air curtain can easily destroy the weakened groove after it expands, and release it from the ceiling. For the safety protection of the occupants, the ab...

Abstract

The invention discloses a weakening structure for expansion of a car roof auxiliary safety air curtain. The weakening structure comprises an interior roof. Weakening grooves formed in the length direction of the interior roof are formed in the two sides in the width direction of the interior roof. The weakening structure for expansion of the car roof auxiliary safety air curtain is characterized in that cutting openings formed in the length direction of the weakening grooves are formed in the weakening grooves and are formed at equal intervals in the length direction of the weakening grooves.The weakening structure for expansion of the car roof auxiliary safety air curtain has the advantages that the structural shape is simple, the aesthetics of interiors is ensured, meanwhile, the safetyair curtain can be released smoothly from the roof, and the safety of a whole car is improved advantageously.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a weakened structure for assisting the deployment of a safety air curtain on an auto roof. Background technique [0002] In order to protect the safety of the occupants, car companies have conducted various safety tests on the entire vehicle and related components, one of which is the side air curtain blast test on the roof of the car interior. The side air curtain is installed on the side of the interior roof of the car and in the space formed by the interior panels adjacent to the interior roof and the body. When the vehicle collides, the side air curtain should be able to be released from the side of the interior roof smoothly to protect the occupants. safety. Since the material used for the interior roof has good toughness and hardness, it is difficult for the interior roof to fall off from the joint of the B-pillar and C-pillar trim panels during the side air curtain bla...
