Problems solved by technology

The more or less uniform stiffness and thermal expansion on the surface of the uniform perforated sheet metal reinforcement does not match well with the irregularities in the reinforcement panels and airbag covers, which are not compatible with the reinforcement and safety under extreme loads of an inflated airbag. Deterioration of the bearing strength of the joint between the airbag cover and adjacent areas exacerbates failures due to expansion and deformation
Due to the limited strength of the press-fit connection of the reinforcement to the reinforcement panel and airbag cover, there is a constant risk of the reinforcement separating or peeling off from the airbag cover and reinforcement panel material, resulting in damage to the airbag
Besides that, pressing the reinforcements into the surface of the complete reinforced panel means an additional production operation which makes the production of the instrument panel more expensive

Embodiment Construction

[0018] Reinforcement panel 2 with integral airbag cover 1, comprising a metal reinforcement 4, the panel is made of a polypropylene based material by injection molding into a metal mold, wherein during the manufacturing process, the reinforcement 4 is first inserted Into the cavity of a reinforced panel 2 mold, after closing the mold, the reinforcement 4 is wrapped by the material of the molten reinforced panel 2, which fills the entire mold cavity.

[0019] Thus, the stamped sheet metal reinforcement 4 not only has openings 7 and profiled protrusions 8a, 8b on its two parts 4a, 4b, but also positioning bosses 9a, 9b, 9c to fix the reinforcement 4 in the injection mold. The correct position in order to prevent the reinforcing member 4 from deviating from its accurate predetermined position during the injection of the melt. For this reinforcement design, the locating bosses 9a, 9b, 9c come in three different styles: the edge locating boss 9a is an outwardly bent strip stamped o...

Abstract

A meter panel with integrated cover of safety air bag is disclosed. When the safety air bag is expanded, its cover is separated from the reinforced panel. It the reinforced panel, said cover and the adjacent region of reinforced panel are reinforced by the metallic sheet which has opening, shaping bosses and locating bosses. The process for preparing the reinforced panel is also disclosed.

Description

field of invention [0001] The invention relates to a fixed protection system for front seat occupants in passenger cars and in motor vehicles. Background of the invention [0002] Airbags are a vital part of the comprehensive protection of motor vehicle occupants. Airbags for front-seat occupant protection are usually located inside the instrument panel, as close as possible to the head of a belted occupant in the event of a frontal collision. From the perspective of airbag operation, the airbag cover must be reliably and easily opened under the action of inflation pressure, so as to make way for the airbag to deploy into the occupant space without causing damage to the airbag. Do not allow any parts or debris that could cause occupant injury or air bag damage to come off the air bag cover or instrument panel assembly. Absolute functional reliability is required at an acceptable cost. Purely for aesthetic reasons, it is often required that the airbag be invisible until de...
