The retainer has outlets adjacent to both ends of the gas generator in a longitudinal direction of the gas generator that is accommodated in the retainer.
1. An occupant leg restraining device, comprising:
an airbag that expands in front of a leg region in a vehicle;
a gas generator that inflates the airbag by ejecting gas; and
a retainer that accommodates the gas generator and the airbag,
wherein the retainer has an opening, a bottom plate which is opposite the opening and to which the gas generator is fixed, and side openings formed at sides adjacent to both ends of the bottom plate, both ends of the gas generator in a longitudinal direction being located in the side openings away from side plates of the retainer.
2. The occupant leg restraining device according to claim 1 , wherein the side 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 the side openings formed adjacent to the both ends of the gas generator.
4. The occupant leg restraining device according to claim 1 , wherein said side openings face obliquely with respect to the bottom plate.
5. The occupant leg restraining device according to claim 4 , wherein the retainer further includes end plates which interconnect the side plates, and wherein the opening is defined by the end plates and the side plates.
6. The occupant leg restraining device according to claim 5 , wherein one of the end plates has ribs adjacent to the side openings, the ribs extending along the side openings to reinforce the one of the end plates.
7. 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:
an opening, a bottom plate opposite the opening, side plates defining two sides of the opening, end plates which interconnect the side plates, and side openings formed at sides adjacent to both ends of the bottom plate below the side plates, a gas generator being accommodated in the retainer and fixed to the bottom plate such that the both ends of the gas generator are located in the side openings away from the side plates of the retainer.
8. The retainer according to claim 7 , wherein said side openings face obliquely with respect to the bottom plate.
9. The retainer according to claim 8 , wherein the opening is defined by the end plates and the side plates.
