Steering column mounted knee airbag device
In a knee airbag device mounted on a steering column, an opening that provides a workspace when a wire harness connector that extends from the steering column is connected to a wiring connector provided at one end portion of an inflator is formed in a side wall of a lower cover (or column cover) opposite the connector of the inflator. By using the opening, the connector of the wire harness may be easily connected to the connector of the inflator, which is mounted transversely with respect to the axial direction of the steering column. The opening is closed by a lid.
1. A knee airbag device mounted on a steering column of a vehicle, comprising:
a knee airbag module that is fixed to a vehicle lower side of the steering column, and includes a folded knee airbag, an inflator that supplies gas to the knee airbag, and a module case that houses the knee airbag and the inflator;
a wiring connector provided at one end of the inflator;
a connector of a wiring harness that extends from the steering column and connects with the wiring connector provided at one end of the inflator;
a column cover that covers a rear end portion of the steering column;
a notch that provides a working space for connecting the connector of the wire harness and the wiring connector provided at the one end of the inflator, the notch being formed in a side wall of a lower cover that forms a lower portion, with respect to the vehicle, of the column cover, at a location opposite the wiring connector so as to be open on an upper side, with respect to the vehicle, of the side wall; and
a lid that closes the notch after the wiring harness is connected, the lid being formed on an upper cover that provides a vehicle-upper-side portion of the column cover so as to protrude downward, with respect to the vehicle, from a vehicle-lower side end portion of the upper cover and being mounted in the notch from the upper side with respect to the vehicle.
