Abstract
An automotive Passenger Side Inflatable Restraint (PSIR) hidden door system contained in an automotive instrument panel and a method of scoring the PSIR door system. The system includes forward and rearward doors hingedly connected at first and second hinges, respectively, to a PSIR airbag chute. The system further includes a common tear line of reduced material thickness integrally joining the forward and rearward doors. The common tear line has a substantially non-linear shape with first and second linear ends.
Claims21
A method of scoring an automotive Passenger Side Inflatable Restraint (PSIR) hidden door system for a vehicle having an instrument panel, the method comprising the steps of:
- providing a PSIR door system having a forward door formed from at least a portion of the instrument panel and a rearward door formed from at least a portion of the instrument panel, wherein the forward door is integrally joined to the rearward door via a common tear line, the forward and rearward doors being hingedly connected at first and second hinges, respectively, to a PSIR airbag chute;
- providing a scoring device to score the common tear line joining the forward and rearward doors;
- scoring the common tear line with the scoring device to form a region of reduced thickness having a substantially non-linear design with first and second linear ends;
- and
- welding the PSIR airbag chute.

- forward and rearward doors formed from at least a portion of the instrument panel and hingedly connected at first and second hinges, respectively, to a PSIR airbag chute;
- and
- a common tear line of reduced thickness integrally joining the forward and rearward doors, the common tear line including a substantially non-linear shape with first and second linear ends.
An automobile having an instrument panel including a generally H-shaped pattern PSIR hidden door system comprising:
- forward and rearward doors formed from at least a portion of the instrument panel and hingedly connected at first and second hinges, respectively, to a PSIR airbag chute;
- a first side tear line of reduced thickness defining at least a portion of the forward and rearward doors;
- a second side tear line of reduced thickness defining at least a portion of the forward and rearward doors;
- and
- a common tear line of reduced thickness extending from the first side tear line to the second side tear line and integrally joining the forward and rearward doors, wherein the common tear line has a substantially non-linear shape with first and second linear ends and wherein the first linear end of the common tear line meets the first side tear line and wherein the second linear end of the common tear line meets the second side tear line.
