Abstract: A process for preweakening the inside of an automotive trim piece cover layer of various constructions by use of a laser beam so as to enable formation of an air bag deployment opening in the trim piece formed at the time the air bag deploys. The laser beam impinges the inside surface of the cover to form a groove scoring or spaced perforations to form a preweakening pattern. A robot arm may be used to move a laser generator so as to form the preweakening pattern. The laser beam can be controlled in accordance with sensed conditions to achieve accurate preweakening, and may also be used to trim substrate panels and to perform other cutting operations.

In a second embodiment detonating cord enclosed in a metal tube is employed with a series of holes directing the energy of detonation to sever the panel skin material. In a third embodiment a split sleeve having explosive coating on the inside is used to create a flame front severing the panel skin in the appropriate pattern.

Abstract: Process and apparatus for precision scoring a workpiece of variable thickness and/or shape in which the thickness of the workpiece at points along a trace pattern is first determined, and a variable depth groove is thereafter formed by laser scoring which is controlled in correspondence with the previously determined thickness values. These values can be determined by scanning opposite surfaces on the surface of a locating fixture and a surface of the workpiece. Robot manipulators are used for scanning and scoring, and the power of the laser and/or the trace velocity are controlled to vary the degree of scoring. The scoring is used to special advantage for precision preweakening of auto trim pieces for creating an air bag deployment opening.

Abstract: A pretreatment for a decorative leather covering layer overlying an air bag deployment opening in an automotive trim piece, the pretreatment results in an effective preweakening of the leather to be readily severed by the forced opening of an underlying hinged door panel. The pretreatment uses a hardening agent applied to the inside of the leather coveringlayer along a strip area extending in a pattern to match the unhinged sides of the door panel. The hardening agent saturates the leather in the strip area to 50-75% of the skin thickness. The leather covering layer has a notch groove formed therein extending along the middle of the strip area in the door pattern, the hardening rendering the leather notch sensitive so as to be effectively preweakened.

Abstract: An installation and is disclosed for mounting an air bag system in an opening in an instrument panel. A stabilizer frame is fixed around the opening in an instrument panel substrate and anchored to a fixed substructure, restraining bulging movement of the instrument panel to rapidly develop shearing stresses in the covering layer by the pressure exerted by the deployment door substrate panel as it is pushed open by the inflating air bag.

Abstract: An air bag installation is disclosed in which a flattened tube is expanded by a flow of pressurized gas from the air bag inflator or a separate source when the air bag system is deployed. The resulting tube expansion drives a cutting edge to sever an opening in a covering layer disposed over a substrate panel of an interior trim structure. A pyrotechnic charge may be used to augment the flow of pressurized gas. The tube may alternatively form an integral part of the instrument panel or the air bag assembly.
