Abstract

The glove box door includes an outer panel constituting a rear circumferential wall, an inner panel constituting a front circumferential wall, an airbag apparatus located between the outer panel and inner panel, a plurality of reinforcing ribs and void spaces formed around the airbag apparatus. The airbag apparatus includes a case that encases an airbag and an inflator and opens toward the rear, a holder that mounts the case on the outer panel, and a door that allows airbag emergence. The holder includes a joint flange and coupled to the outer panel by the joint flange. The outer panel is fabricated of hard synthetic resin having enhanced rigidity relative to the holder. A pair of mounting elements are assembled with the holder in such a manner as to be prevented from forward or backward movement. Mounting tongues formed on the case are secured to the mounting elements which are assembled with the holder and thus the case is mounted to the outer panel.

Claims

1. A door of a glove box for installation in front of a seat of a vehicle, comprising:

an outer panel fabricated of synthetic resin and constituting a rear outer circumferential wall of the glove box door, the outer panel including an outer door region provided therearound with a weakened tearable portion;

an inner panel coupled to the outer panel and constituting a front outer circumferential wall of the glove box door;

an airbag apparatus located between the outer panel and the inner panel and comprising;

an inflatable airbag for emergence from the outer door region of the outer panel;

an inflator that feeds inflation gas to the airbag;

a case that houses and holds the airbag and inflator, including;

a circumferential wall;

a front wall closing off the front side of the circumferential wall;

an opening that opposes the front wall for allowing emergence of the airbag; and

a pair of mounting tongues that are formed on opposite sides of the circumferential wall;

a holder that is fabricated of synthetic resin, the holder being coupled to the outer panel and holding the case in order to mount the case to the outer panel, including;

a circumferential wall that is mounted around the case and extend in a generally anteroposterior direction;

a holding panel that is joined with and extends from a rear end of the circumferential wall in such a manner as to cover the opening of the case, the holding panel being coupled to and holding the outer door region of the outer panel and provided with a flexible hinge located proximate the rear end of the circumferential wall; and

a joint flange extending from the rear end of the circumferential wall and coupled to an area of the outer panel encircling the outer circumference of the tearable portion; and

a pair of mounting elements assembled with the holder in such a manner as to be prevented from forward or backward movement for assisting the mounting of the case to the outer panel, the mounting tongues of the case being secured to the mounting elements by fixing means; and

a plurality of reinforcing ribs extending between and connecting the outer panel and inner panel around the airbag apparatus in such a manner as to form void spaces between the outer panel and inner panel, wherein;

the outer panel is fabricated of rigid synthetic resin relative to the holder; and

the outer door region of the outer panel and the holding panel of the holder form, in combination, a door that covers the opening of the case and opens at airbag deployment due to tear of the tearable portion of the outer door region to provide an emergence opening that allows emergence of the airbag.

2. The glove box door as set forth in claim 1, wherein:

each of the mounting elements is formed into a generally plate shape;

the holder includes a pair of mounting beds each of which includes a front regulating region that regulates movement of the mounting element on the front side and a rear regulating region that regulates movement of the mounting element on the rear side; and

each of the mounting elements is inserted into a space between the front regulating region and rear regulating region and thus assembled with the holder.

3. The glove box door as set forth in claim 2, wherein:

the front regulating region of each of the mounting beds includes a front wall that is connected to the circumferential wall of the holder and regulates movement of the mounting element on the front side, the front wall including a round through hole for receiving a bolt acting as the fixing means, and a pair of support walls that extend from opposite ends of the front wall toward the joint flange and coupled to the joint flange while being connected to the circumferential wall of the holder, the front regulating region thus having a “

U”

shaped section;

each of the mounting elements includes a screw hole for receiving the bolt; and

the rear regulating region of each of the mounting beds is coupled to the circumferential wall and joint flange of the holder and supports the vicinity of the screw hole of the mounting element at more than one locations from the rear.

4. The glove box door as set forth in claim 1, wherein:

the inner panel includes a cover panel that is fabricated of synthetic resin and located in front of the airbag apparatus and a peripheral panel that is fabricated of synthetic resin and located around the cover panel, the cover panel being coupled to the peripheral panel; and

the reinforcing ribs are integral with either the outer panel or the peripheral panel of the inner panel and welded to the peripheral panel or the outer panel.

5. The glove box door as set forth in claim 1, wherein the inner panel is formed of a single plate-shaped material.

6. The glove box door as set forth in claim 1, wherein at least part of the reinforcing ribs located in the vicinity of the holder is integral with the outer panel.
