Abstract

A collision object protection device inflates and expands an air bag on a vehicle as soon as a collision of a collision object with the vehicle is detected or predicted. The collision object protection device includes: the air bag having a main body portion that expands along a lower part of a front windshield glass of the vehicle, a pair of pillar portions that expand along front pillars of the vehicle, and a pair of pillar base portions that connect the main body portion and the pair of pillar portions; and at least one inflator for supplying a gas to the main body portion of the air bag. A partition wall having one or more openings is arranged inside the air bag respectively at a boundary between the main body portion and the pillar base portion.

Claims

1. A collision object protection device, which inflates and expands an air bag on a vehicle as soon as a collision of a collision object with the vehicle is detected or predicted, the collision object protection device comprising:

the air bag consisting of a main body portion which expands along a lower part of a front windshield glass of the vehicle,

a pair of pillar portions which expand along front pillars of the vehicle, and a pair of pillar base portions which connect the main body portion and the pair of pillar portions; and

a pair of inflators to which the main body portion of the air bag is attached to supply a gas to the main body portion,

wherein the main body portion is provided with a gather between the inflators.

2. A collision object protection device according to claim 1, wherein a partition wall having one or more openings is arranged inside the air bag respectively at boundaries between the pillar base portions and the pillar portions.

3. A collision object protection device according to claim 2, wherein a vent hole for discharging the gas is provided at each pillar portion in such a position that the gas is discharged oppositely to the vehicle.

4. A collision object protection device according to claim 1, wherein a vent hole for discharging the gas is provided at each pillar portion in such a position that the gas is discharged oppositely to the vehicle.
