Definitions
- Lumbar restraint airbag device and seat cushion device using the same
- the present invention relates to a vehicle airbag device having a waist restraint function for restraining an occupant by being restrained by a seat in the event of a collision, for example.
- Patent Document 1 Japanese Patent Laid-Open No. 5-229378
- Patent Document 2 JP-A-10-217818
- Patent Document 3 British Patent GB2357466
- the present invention has been made in view of the above situation, and an object of the present invention is to provide a waist restraint airbag device that contributes to improvement of the waist restraint performance of an occupant.
- a waist restraint airbag device is disposed in or under a seat cushion of a vehicle, and is seated on the seat cushion in an emergency.
- a waist restraining airbag device that restrains the waist of an occupant and restricts forward movement, comprising: an airbag that is accommodated in an inflatable and deployable state; and a gas supply device that supplies inflation gas into the airbag. Yes.
- the airbag can be deployed by inclining from the direction perpendicular to the bottom surface.
- the inclination in the airbag deployment direction includes the front and rear of the vehicle.
- the deployment direction is tilted forward of the vehicle, it is possible to avoid a situation where an occupant gets on the upper part of the airbag and obtain a sufficient restraining force.
- the deployment direction is inclined toward the rear of the vehicle, the occupant's waist (pelvis) can be restrained immediately after deployment. In any case, it is not necessary to change the arrangement of the airbag device itself under the seat where there are many restrictions on installation, so that it can be applied to various types of vehicles.
- the airbag includes a cylindrical main body portion extending in the left-right direction of the vehicle; and covers both side surfaces (left and right side surfaces) of the main body portion, and is substantially parallel to the four sides when deployed. And a side surface portion having a shape. And the airbag can be made into the structure folded up and down stepwise toward the vehicle front side or back side.
- FIG. 1 is an explanatory view showing a use state (installation state) of a waist restraint airbag device according to an embodiment of the present invention, and shows a state before deployment.
- the airbag device 10 for restraining the lumbar region according to the embodiment is installed inside or below the seat cushion 12 and is used by an occupant M seated on the seat cushion 12 in an emergency (vehicle collision, etc.). Constrains the waist and restricts forward movement.
- the airbag device 10 includes an airbag (inflator bag) 14 that is accommodated in a state in which at least a part of the bottom surface (20a) is fixed and can be inflated and deployed; a gas supply device that supplies inflation gas into the airbag 14 As an inflator 18.
- a material of the air bag 14 a metal sheet having a thickness of about 0.4 mm or a molded body of a thick resin sheet can be used.
- FIG. 2 is a side view showing the structure of the airbag device 10.
- the airbag 14 can be deployed with the bottom surface (20a) inclined toward the vehicle traveling direction rather than the vertical direction V. This tilt direction is indicated by DO.
- a broken line 14b shows a deployment state of an airbag having a rectangular side surface as in the prior art.
- Dashed line 14a is the side of the approximately parallelogram
- the deployment state of the airbag 14 which concerns on a present Example which has a surface (22) is shown.
- the side surface of the airbag 14 corresponds to an end surface in the width direction (left-right direction) of the vehicle seat.
- the deployment direction of the airbag 14 can be said to be a direction parallel to the left and right (occupant front-rear direction) sides when the side surface 22 when deployed is a substantially parallelogram.
- FIG. 3 is a perspective view showing the structure of the airbag 14.
- the airbag 14 includes a cylindrical main body portion 20 that extends in the left-right direction of the vehicle (winded in the front-rear direction); and two side surface portions 22 that block both side surfaces of the main body portion 20.
- the part indicated by the short diagonal line is the welded part. That is, a position where both end portions of the belt-shaped metal plate constituting the cylindrical main body portion 20 are in contact with each other, and a position where the left and right side portions (upper and lower end portions of the cylinder) and the side surface portion 22 are in contact with each other are welded. As shown in FIGS.
- the airbag 14 is folded up and down in a stepped manner toward the front side of the vehicle in the accommodated state before deployment.
- the side surface portion 22 in a state before the airbag 14 is folded has a shape having a protruding portion 22a extending forward of the vehicle and a protruding portion 22b extending rearward.
- the protrusions 22a and 22b are formed at positions close to the upper and lower surfaces of the airbag, respectively.
- FIG. 4 is a schematic diagram showing a change in shape of the side surface of the airbag of the airbag apparatus according to the embodiment, where (A) shows a state in the middle of folding and (B) shows a deployed state.
- FIG. (A) shows a state in the middle of folding
- FIG. (B) shows a deployed state.
- FIG. (A) shows a state in the middle of folding
- FIG. (B) shows a deployed state.
- the deployment direction of the airbag 14 is shifted to the vehicle traveling direction (forward) or rearward without changing the position of the device 10 disposed under the seat. It is in.
- a force or other shape in which the developed shape of the side surface portion 22 is a substantially parallelogram For example, as shown in FIG. 5, an airbag 114 having an oval side surface portion can be employed.
- D1 indicates the deployment direction
- the deployment direction Dl in this case corresponds to the case where a parallelogram having a minimum area with the bottom surface 20a as a base is virtually created, and the airbag 114 (side surface portion) is inscribed in the parallelogram. It can be said that the direction is parallel to the left and right sides of the parallelogram.
- FIG. 4 is an explanatory view showing a use state (installation state) of the waist restraint airbag device 10 according to the embodiment, and shows a state at the time of inflation and deployment.
- the inflator 18 When the inflator 18 is activated during a sudden deceleration due to a frontal collision of the vehicle, high-pressure gas is ejected from the inflator 18 into the airbag 14.
- the airbag 14 is inflated and deployed when the jetted high-pressure gas is filled inside, and pushes the seat cushion 12 upward as shown in FIG.
- the airbag is obliquely forward in the deployment direction, but can be inclined rearward or laterally depending on the purpose.
- the airbag deployment direction is tilted backward, the occupant's waist (pelvis) can be restrained immediately after the airbag deployment.
- FIG. 1 is an explanatory view showing a use state (installation state) of a waist restraining airbag device according to an embodiment of the present invention, and shows a state before deployment.
- FIG. 2 is a side view showing the structure of the airbag apparatus according to the embodiment.
- FIG. 3 is a perspective view showing the structure of the airbag of the airbag apparatus according to the embodiment.
- FIG. 4 is a schematic view showing a change in shape of the side surface of the airbag of the airbag apparatus according to the embodiment, where (A) shows a state during folding and (B) shows a deployed state.
- FIG. 5 is an explanatory view showing a use state (installation state) of the waist restraint airbag device according to the embodiment, and shows a state at the time of inflating and deploying.
- FIG. 6 is a schematic diagram showing a deployed state (side surface portion) of an airbag used in an airbag apparatus according to another embodiment of the present invention.
