Knee bolster of glove box for vehicle
A knee bolster of a glove box for a vehicle is provided. The knee bolster of a glove box increases the stiffness of the front surface of the glove box with which the knees of a passenger may collide when a vehicle collision occurs, and thus restrains the knees of the passenger from rushing into the glove box. The knee bolster of a glove box for a vehicle can reduce the weight of the knee bolster, the production cost thereof, and a number of manufacturing processes compared to the conventional knee bolster for passenger seats.
1. A knee bolster provided on a glove box for a vehicle,
comprising:
a composite-material reinforced plate installed on a front surface of the glove box with which knees of a passenger collide when a vehicle collision occurs,
wherein the composite-material reinforced plate is formed of a plurality of composite-material sheets, in which continuous fibers are oriented in one direction, the plurality of composite-material sheets being stacked in a predetermined pattern on a basis of a continuous-fiber orientation, and
wherein the composite-material sheets stacked to form the composite-material reinforced plate comprise a composite-material sheet having continuous fibers oriented to extend in a transverse direction thereof, a composite-material sheet having continuous fibers oriented to extend in a longitudinal direction thereof, and a composite-material sheet having continuous fibers oriented to extend in an inclined direction thereof.
2. The knee bolster of claim 1 , wherein a housing to which the composite-material reinforced plate is mounted is provided on the front surface of the glove box, and a front cover covering the housing to which the composite-material reinforced plate is mounted is provided on the front surface of the glove box.
3. The knee bolster of claim 2 , wherein the housing comprises: a plurality of fusing ribs passing through the composite-material reinforced plate and bonded to the front cover; and a plurality of hooks configured to fix the composite-material reinforced plate to the housing.
4. The knee bolster of claim 1 , wherein a first support bracket and a second support bracket that are configured to restrain the knees of the passenger from rushing into the glove box are installed between a cowl cross bar disposed in front of the glove box and the front surface of the glove box on which the composite-material reinforced plate is installed.
5. The knee bolster of claim 1 , wherein the composite-material reinforced plate is configured by stacking the composite-material sheets having different continuous-fiber orientations according to a predetermined ratio on a basis of an entire thickness of the composite-material reinforced plate.
6. The knee bolster of claim 1 , wherein each of the composite-material sheets is formed by impregnating the continuous fibers having one identical orientation into thermoplastics.
