Abstract

A side bolster adjusting apparatus of a seat of a vehicle for guiding a developing direction of a side airbag may include a side airbag developing direction guide plates integrally fixed to a seatback frame to guide a developing direction of the side airbag, side bolster adjusting plates hinged to rear ends of the side airbag developing direction guide plates, an airbag disposed between the side airbag developing direction guide plates and the side bolster adjusting plates to expand and shrink and to adjust positions of the side bolster adjusting plates, and a pneumatic control unit controlling expansion and shrinkage of the airbag.

First claim

What is claimed is:

1. A side bolster adjusting apparatus of a seat of a vehicle for guiding a developing direction of a side airbag, the apparatus comprising:
a side airbag developing direction guide plates integrally fixed to a seatback frame to guide a developing direction of the side airbag;
side bolster adjusting plates hinged to rear ends of the side airbag developing direction guide plates;
an airbag disposed between the side airbag developing direction guide plates and the side bolster adjusting plates to expand and shrink and to adjust positions of the side bolster adjusting plates; and
a pneumatic control unit controlling expansion and shrinkage of the airbag,
wherein each of the side airbag developing direction guide plates includes a hook integrally formed at a front end thereof and pressed into a supporting wire connected to the seatback frame, while a rear end thereof is bolted to the seatback frame.

2. The side bolster adjusting apparatus of claim 1 , wherein the side airbag developing direction guide plates are arranged near inside and front positions of the side airbag and obliquely toward between sides of a passenger and doors.

3. The side bolster adjusting apparatus of claim 1 , wherein each of the side airbag developing direction guide plates includes a front end of arranged as a free end, and a rear end has a bolt coupling end closely attached to an inner surface of the seatback frame and a closely attaching end closely attached to an outer surface of the seatback frame, while the bolt coupling end and the closely attaching end are spaced apart from each other and integrally formed with each other.

4. The side bolster adjusting apparatus of claim 1 , wherein the side airbag developing direction guide plates are integrally molded to protrude from both sides of the seatback frame when the seatback frame is manufactured.

5. The side bolster adjusting apparatus of claim 1 , wherein the pneumatic control unit comprises:
a pneumatic pump serving as an air source;
a pneumatic valve supplying and interrupting air from the pneumatic pump; and
a controller controlling opening/closing of the pneumatic vale and turning on/off of the pneumatic pump based on a signal of a switch manipulated by a passenger.

6. A side bolster adjusting apparatus of a seat of a vehicle for guiding a developing direction of a side airbag, the apparatus comprising:
a side airbag developing direction guide plates integrally fixed to a seatback frame to guide a developing direction of the side airbag;
side bolster adjusting plates hinged to rear ends of the side airbag developing direction guide plates;
an airbag disposed between the side airbag developing direction guide plates and the side bolster adjusting plates to expand and shrink and to adjust positions of the side bolster adjusting plates; and
a pneumatic control unit controlling expansion and shrinkage of the airbag,
wherein each of the side airbag developing direction guide plates includes a front end of arranged as a free end, and a rear end has a bolt coupling end closely attached to an inner surface of the seatback frame and a closely attaching end closely attached to an outer surface of the seatback frame, while the bolt coupling end and the closely attaching end are spaced apart from each other and integrally formed with each other.

7. The side bolster adjusting apparatus of claim 6 , wherein the side airbag developing direction guide plates are arranged near inside and front positions of the side airbag and obliquely toward between sides of a passenger and doors.

8. The side bolster adjusting apparatus of claim 6 , wherein each of the side airbag developing direction guide plates includes a hook integrally formed at a front end thereof and pressed into a supporting wire connected to the seatback frame, while a rear end thereof is bolted to the seatback frame.

9. The side bolster adjusting apparatus of claim 6 , wherein the side airbag developing direction guide plates are integrally molded to protrude from both sides of the seatback frame when the seatback frame is manufactured.

10. The side bolster adjusting apparatus of claim 6 , wherein the pneumatic control unit comprises:
a pneumatic pump serving as an air source;
a pneumatic valve supplying and interrupting air from the pneumatic pump; and
a controller controlling opening/closing of the pneumatic vale and turning on/off of the pneumatic pump based on a signal of a switch manipulated by a passenger.
