When the lower end of a glove box 5 is pivoted at the lower end of the glove box 2, and when the main body portion 8 of the glove box 5 is housed in the glove box case 2, the right and left end parts at the inner wall surface of a cabin in the glove box 5 are faced to the right and left flanges of the glove box 2 respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorber provided around a glove box of a vehicle for protecting a vehicle occupant.

[0002]

2. Description of the Related Art Conventionally, in order to protect an occupant in a passenger seat of a vehicle in the event of a vehicle collision, as shown in FIGS. The front wall 3 of the glove box case 2 opened rearward and downward of the vehicle is fixed by screws 4, and the lower end of the glove box 5 is pivotally supported at the lower end of the glove box case 2, and the interior side wall surface 6 of the glove box 5 in the vehicle interior
With the left and right ends facing the flanges 7 on the left and right ends of the glove box case 2, the glove box 5
The main body portion 8 is housed in the glove box case 2, and the glove box 5 is assembled so as to be rotatable from the inside of the glove box case 2 to the vehicle interior side behind the vehicle, and is formed of a bent plate material. The front ends of the knee absorbers 9 and 9 are fixed to the deck cross member 11 with bolts 10 respectively, and the projections 12 at the rear ends of the knee absorbers 9 and 9 are respectively inserted through holes 13 formed in the glove box case flange 7 so as to be in the rear of the vehicle. And is fitted into a box-shaped catch 15 fixed to a steel plate insert 14 built in the glove box wall surface 6. Reference numeral 16 denotes a rubber damper attached to the glove box case flange 7.

[0003] Therefore, in the event of a collision of the vehicle, when the occupant's knee in the front passenger seat is displaced forward and collides with the side wall surface 6 of the glove box 5, the glove box case 2 or the glove box 5 is deformed. Is displaced to the front of the vehicle, and the catch 15 presses the projections 12 at the rear ends of the knee absorbers 9 and 9 toward the front of the vehicle, respectively, so that the knee absorbers 9 and 9 bend more greatly. As a result, the occupant can be effectively protected.

However, in this case, when the glove box 5 housed in the glove box case 2 is opened by rotating it to the rear of the vehicle, the glove box case flange 7 protrudes from the knee absorbers 9 and the projections 12 at the rear end.
However, there is a drawback that the occupant gives a feeling of foreign matter to the occupant and has a very poor appearance.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an occupant cushioning device which does not impair the appearance of an occupant by opening and closing a glove box in a vehicle.

[0006]

For this reason, a shock absorber according to the present invention comprises a glove box case and a main body portion housed in the glove box case, and the glove box case is rotated to the rear of the vehicle by the glove box case. A freely pivoted glove box and one end fixed to the vehicle body side and the other end fixed to the front side of the end flange of the glove box case in the vehicle front direction to absorb energy by deformation according to the load in the vehicle front-rear direction. A rigid insert, which is provided with a knee absorber and is embedded in the side wall surface of the glove box in the vehicle interior, is configured to overlap the flange in the vehicle front-rear direction.

Therefore, when the passenger in the passenger seat is displaced to the front of the vehicle and collides with the glove box at the time of collision of the vehicle, when the main body of the glove box is stored in the glove box case, the glove box is located on the vehicle interior side. Since the rigid insert built into the wall overlaps the end flange of the glove box case in the front-rear direction of the vehicle, the glove box presses the other end of the knee absorber forward of the vehicle through the end flange of the glove box case. By deforming the knee absorber, one end of which is fixed to the vehicle body, the kinetic energy of the occupant can be absorbed and the occupant can be protected from vehicle collision, while the glove box can be moved from the glove box case to the vehicle behind the vehicle. When pivoted open to the indoor side, the other end of the knee absorber is Because it is fixed to the vehicle front side of the end flange in the scan, and the other end is covered from the inside of the passenger compartment by the end flange of the glove box casing,
It is blindfolded by the occupants in the cabin.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention shown in the drawings will be described by assigning the same reference numerals to the same parts as those of the conventional device. 1 to 3, front ends of knee absorbers 20, 20 made of bent plate materials are fixed to deck cross members 11 by bolts 10, and arms 21 extending substantially downward are respectively provided at rear ends of knee absorbers 20, 20. The arm portions 21 are fixed to the vehicle rear side of the left and right flanges 7 of the glove box case 2 by heat welding or rivets, and the glove box case 2 is positioned.

The glove box case 2 is opened rearward and downward of the vehicle. The lower end of the glove box 5 is pivotally supported at the lower end. When the main body 8 of the glove box 5 is stored in the glove box case 2, the glove box The left and right ends of the interior side wall surface 6 of the box 5 face the flanges 7 at the left and right ends of the glove box case 2, respectively, and the left and right ends of the steel insert 14 built into the glove box wall surface 6 are respectively glove box cases. 2 overlaps the left and right end flanges 7 in the front-rear direction of the vehicle, and from the state in which the main body portion 8 of the glove box 5 is stored in the glove box case 2, the entire glove box 5 is rotatable rearward in the vehicle. Assembled as it is. Reference numeral 16 denotes a rubber damper attached to the glove box case flange 7.

Therefore, at the time of collision of the vehicle, when the occupant's knee in the passenger seat is displaced forward of the vehicle and the main body portion 8 collides with the side wall surface 6 of the glove box 5 housed in the glove box case 2, As shown by a two-dot chain line in FIG.
Presses the arm portions 21 of the knee absorbers 20 and 20 via the flange 7 of the glove box case 2 toward the front of the vehicle, and the glove box case 2 and the glove box 5 are both displaced toward the front of the vehicle.
Since each 20 is bent more greatly, the kinetic energy of the occupant is absorbed by the deformation, so that the occupant can be effectively protected.

When the glove box 5 is opened by rotating the glove box 5 backward from the state in which the main body portion 8 of the glove box 5 is stored in the glove box case 2,
Arm portions 21 at the rear end of knee absorbers 20 and 20 are arranged on the front side of the left and right flanges 7 of the glove box case, respectively. Is completely blindfolded from the front, so that no special projection is generated on the surface of the glove box case 2 on the vehicle interior side when the glove box 5 is opened and closed, and the appearance is remarkably improved. be able to.

[0012]

In the shock absorber according to the present invention, when the glove box is opened by rotating the glove box rearward from the glove box case, the other end of the knee absorber is located on the front side of the end flange of the glove box case on the vehicle front side. The glove box case is fixed and the knee absorber is covered from the inside of the cabin by the glove box case, and is hidden from the occupants in the cabin. There is no advantage at all, and there is an advantage that the appearance can be significantly improved.
