Abstract

To provide an occupant leg restraining device and a retainer capable of improving flexibility in the layout of a gas generator.

An occupant leg restraining device includes a knee airbag 18 that expands in front of legs of an occupant in a vehicle; a gas generator 20 that inflates the knee airbag 18 by ejecting gas; and a retainer 16 that accommodates and holds the gas generator 20 and the folded knee airbag 18. The retainer 16 has outlets 16h adjacent to both ends of the gas generator 20 in a longitudinal direction of the gas generator 20 that is accommodated in the retainer 16.

Claims

1. An occupant leg restraining device, comprising:

an airbag that expands in front of legs of an occupant in a vehicle;

a gas generator that inflates the airbag by ejecting gas; and

a retainer that accommodates the gas generator and the folded airbag, wherein

the retainer has openings adjacent to both ends of the gas generator in a longitudinal direction of the gas generator that is accommodated in the retainer.

2. The occupant leg restraining device according to claim 1, wherein the openings correspond to outlets for drawing a harness connected to the gas generator.

3. The occupant leg restraining device according to claim 1, wherein the retainer has ribs adjacent to the openings formed adjacent to both ends of the gas generator.

4. A retainer for an occupant leg restraining device, the retainer accommodating an airbag and a gas generator that inflates the airbag by generating gas, the retainer comprising:

openings formed adjacent to both ends of the gas generator in a longitudinal direction of the gas generator that is accommodated in the retainer.
