Abstract
A technique is provided effective in preventing liquid from flowing from the exterior of an airbag cover into an airbag housing in a motorcycle airbag apparatus with a structure in which the airbag opening of an airbag housing is covered with an airbag cover. In one form, an airbag apparatus mounted to a motorcycle is constructed such that the upper end of a retainer wall is dispose above webbing through holes so as to prevent liquid influx from the exterior of a module cover through the webbing through holes into a retainer.
Claims18
An airbag apparatus in combination with a motorcycle to which the airbag apparatus is mounted, the combination comprising:
- a body of the motorcycle;
- an airbag;
- an inflator for supplying inflation gas to the airbag for airbag deployment;
- a retainer assembly mounted to the motorcycle body and being configured for housing the airbag therein to prior airbag deployment;
- a tether secured to the motorcycle body;
- an unobstructed opening in the retainer assembly sized for the tether to extend therethrough;
- a portion of the tether in the retainer assembly connected to the airbag so that the tether extends through the unobstructed opening to be secured to the motorcycle body and upon airbag deployment the tether anchors the airbag to the motorcycle body;
- and
- a fluid blocking device of the retainer assembly adjacent the opening that substantially keeps liquid from outside the retainer assembly from accessing the airbag and the inflator in the retainer assembly via the opening.
6 more elements
An airbag apparatus to be mounted to a motorcycle, the airbag apparatus comprising:
- an airbag;
- a retainer for housing the airbag in a folded state and having upstanding side walls extending about an opening through which the airbag is deployed;
- a fixture on at least one of the upstanding side walls a cover portion covering the opening of the retainer and having peripheral side wall portions depending therefrom;
- a fixture-receiving through hole in one of the peripheral side wall portions adjacent to the one upstanding side wall and sized for fitting the fixture therethrough to secure the retainer to the cover portion;
- a tether-receiving through hole in the one peripheral side wall portion that is laterally larger than the fixture-receiving through hole so that the tether-receiving through hole is sized to receive a tether therethrough;
- a fluid blocking device of the retainer assembly adjacent the larger, tether-receiving through hole that substantially keeps liquid from outside the retainer from accessing the airbag in the retainer via the larger tether-receiving through hole.
3 more elements
An airbag apparatus to be mounted to a motorcycle, the airbag housing apparatus comprising:
- an airbag;
- a retainer for housing the airbag in a folded state and having upstanding side walls extending about an opening through which the airbag is deployed;
- a cover portion covering the opening of the retainer and having peripheral side wall portions depending therefrom, with at least one of the peripheral side wall portions secured to at least one of the side walls of the retainer;
- a through hole disposed on one of the peripheral side wall portions;
- and
- a fluid blocking device of the retainer assembly adjacent the through hole that substantially keeps liquid from outside the retainer from accessing the airbag in the retainer via the through hole, wherein the fluid blocking device includes a blocking member mounted to an interior surface of the one of the peripheral walls containing the through hole, with a portion of the blocking member extending down over the through hole.
3 more elements
An airbag apparatus to be mounted to a motorcycle, the airbag apparatus comprising:
- an airbag;
- a retainer for housing the airbag in a folded state and having upstanding side walls extending about an opening through which the airbag is deployed;
- a cover portion covering the opening of the retainer and having peripheral side wall portions depending therefrom, with at least one of the peripheral side wall portions secured to at least one of the side walls of the retainer;
- a through hole disposed on one of the peripheral side wall portions;
- a fluid blocking device of the retainer assembly adjacent the through hole that substantially keeps liquid from outside the retainer from accessing the airbag in the retainer via the through hole;
- and
- tear lines disposed on a portion of the peripheral side wall portions, with the through hole being disposed along a portion of the tear lines.
4 more elements
A motorcycle comprising:
- a body;
- a seat of the body for supporting a rider seated thereon;
- an airbag retainer mounted forwardly of the seat and having side walls about an opening;
- an airbag housed in the retainer in a folded state for being deployed out of the opening and inflated rearwardly upon detection of a front collision of the motorcycle;
- an inflator for supplying inflation gas to the airbag;
- a cover portion covering the open portion of the retainer and having peripheral side wall portions depending therefrom, with at least one of the peripheral side walls attached to the retainer to secure the cover to the retainer;
- a through hole disposed on one of the peripheral side wall portions;
- an elongated tether that extends through the through hole and is secured at a first end to the airbag and at a second end to the body;
- and
- an upper end of one of the retainer side walls extending above the through hole substantially keeps liquid from outside the retainer from accessing the airbag and the inflator in the retainer via the through hole.
