Abstract

In a back portion of a seat back provided with a lumbar support portion 20 and a side support portion 21, a seat back cover 30 for covering a back face of the seat back is provided. The seat back cover 30 is provided with a side portion 32 for covering an air bag module 50 by making a forward end portion, which is extended to the front side of a vehicle, come into contact with the side support portion 21. The side support portion 21 is provided being capable of oscillating to the front side of the vehicle with respect to the lumbar support 20. An air bag module 50 is arranged in an accommodation space 90 provided on the rear side of the side support portion 21.

Claims

1. A seat with an integrated air bag for a vehicle, in a seat back of the seat an accommodation space is formed, an air bag module, in which the air bag is folded, being arranged in the accommodation space, the seat back comprising:

a side cover portion for covering the air bag module and defining a side of the seat back;

a lumbar support portion for supporting a back portion of a passenger; and

a side support portion for supporting a side of a lumbar of the passenger, wherein an end of said side cover portion is normally in engagement with said side support portion, said side support portion cooperating with the side cover portion to define a passageway in communication with said accommodation space and leading to an area of engagement between said side cover portion and said side support portion, wherein

the air bag module is arranged on a rear side of the side support portion in the accommodation space,

the side support portion is oscillated toward a front of the vehicle and away from said side cover portion, which remains generally stationary with respect to the vehicle, such that said side support portion disengages and separates from the side cover portion to create an opening in communication with said passageway by a development pressure of the air bag in the air bag module,

the air bag module is arranged inside an air bag holding member, a cross section of which is substantially U-shaped with a left arm portion and a right arm portion, the front side of the U-shaped air bag holding member is open, and

the air bag module is arranged in the accommodation space together with the air bag holding member.

2. The seat with the integrated air bag according to claim 1, further comprising:

a protruding portion protruding toward the front of the vehicle, provided inside of a side portion of the side cover portion,

a folding back portion, which is folded back to a rear side of the vehicle, provided in an outside end portion of the air bag holding member, wherein the protruding portion is engaged with the folding back portion.

3. The seat with the integrated air bag according to claim 1, wherein the air bag holding member is substantially unchanged in shape after exposure to the development pressure of the air bag.

4. The seat with the integrated air bag according to claim 1, wherein the left arm portion is substantially vertical after exposure to the development pressure of the air bag.

5. The seat with the integrated air bag according to claim 1, wherein the right arm portion is substantially vertical after exposure to the development pressure of the air bag.

6. The seat with the integrated air bag according to claim 1, wherein after exposure to the development pressure of the air bag, the side support portion is separated from the side cover portion in a nondestructive fashion.

7. A seat with an integrated air bag for a vehicle, in a seat back of which an accommodation space is formed, an air bag module, in which the air bag is folded, being arranged in the accommodation space, the seat back comprising:

a cover portion for covering the air bag module;

a lumbar support portion for supporting a back portion of a passenger;

a side support portion for supporting a side of a lumbar of the passenger, wherein

the air bag module is arranged on a rear side of the side support portion in the accommodation space inside an air bag holding member, said air bag holding member having a generally U-shaped cross sectional shape, wherein a front side of the U-shaped air bag holding member is open and the air bag module is arranged in the accommodation space together with the air bag holding member,

the side support portion is oscillated to a front of the vehicle so as to open a portion between the cover portion and the side support portion by a development pressure of the air bag in the air bag module;

a protruding portion extending toward the front of the vehicle provided inside of a side portion of the cover portion; and

a folding back portion, which is folded back to a rear side of the vehicle, provided in an outside end portion of the air bag holding member, wherein the protruding portion is engaged with the folding back portion.
