Abstract

A roof air bag mounting structure includes a frame having a plurality of vertically open spaces therein and bolt holes at opposite ends thereof and air bag cushions provided respectively inside the spaces of the frame. A door allowing the air bag cushion to deploy is provided at the bottom of the frame, and the top surface of the frame is closed to support a deploying force of the air bag cushion. The roof air bag mounting structure can be easily assembled and reduced in weight.

Claims

1. A roof air bag mounting structure comprising:

a frame having at least an open space therein and coupling members at opposite end portions thereof; and

at least an airbag cushion provided inside the at least an open space of the frame, respectively wherein the frame mounts the at least an airbag cushion onto a vehicle body roof by the coupling members,

wherein a door allowing a corresponding air bag cushion to deploy is provided at a bottom of the frame to cover a corresponding open space,

wherein the opposite end portions of the frame curve downwardly in a longitudinal direction thereof, and

wherein the coupling members are disposed laterally of the downwardly curved opposite end portions of the frame.

2. The roof air bag mounting structure in accordance with claim 1, wherein the frame is monolithically formed.

3. The roof air bag mounting structure in accordance with claim 1, wherein the coupling members are symmetrically provided in the opposite end portions of the frame with respect to a longitudinal axis of the frame.

4. The roof air bag mounting structure in accordance with claim 1, wherein the opposite end portions of the frame are formed in a shape conforming to a side of a vehicle body.

5. The roof air bag mounting structure in accordance with claim 1, wherein the frame is elongated at a length corresponding to a width of a vehicle body.

6. The roof air bag mounting structure in accordance with claim 1, wherein the frame has an arc-like shape to prevent the frame from sagging down.

7. The roof air bag mounting structure in accordance with claim 1, wherein the frame is mounted to the vehicle body roof by the coupling members, with the air bag cushion brought into contact with the vehicle body roof, so that the vehicle body roof supports a deploying force of the at least an air bag cushion when the at least an air bag cushion is being deployed.
