Vehicular front bumper structure
First Claim
1. A front bumper structure for a vehicle, comprising:
- a front bumper having a bumper reinforce and a shock absorber; and
a collision detection sensor configured to detect a collision of an object against the front bumper, the collision detection sensor being provided to extend along the bumper reinforce between the bumper reinforce and the shock absorber,wherein the collision detection sensor has an interface part positioned at a first end of the collision detection sensor in a widthwise direction of the vehicle, the first end being on a side of the collision detection sensor that is on a driver side of the vehicle, andwherein a second end of the collision detection sensor in the widthwise direction of the vehicle has no interface part, the second end being on a side of the collision detection sensor that is on a passenger side of the vehicle.

Abstract
In a vehicular front bumper structure having the function of detecting the collision of an object against the front bumper of a vehicle in the vehicle, the length of a front bumper area in widthwise directions of the vehicle, in which area a load applied to the front bumper is detected with a collision detection sensor (104), is more than or equal to a maximum distance in the widthwise directions of the vehicle between the right and left front pillars (A pillars; 107) of the vehicle, the collision detection sensor being provided to extend along a bumper reinforce (103) between the bumper reinforce and a shock absorber (105), the bumper reinforce and the shock absorber forming the front bumper; and the collision detection sensor has an interface part (106) provided at one of the ends of the collision detection sensor in the widthwise directions of the vehicle which one is on the side opposite to a walkway (a right front end in left-hand traffic/a left front end in right-hand traffic).

15. A front bumper structure for a vehicle, comprising:
-
a front bumper having a bumper reinforce and a shock absorber; a collision detection sensor configured to detect a collision of an object against the front bumper, the collision detection sensor being provided to extend along the bumper reinforce between the bumper reinforce and the shock absorber; and load transmission means for transmitting a load to the collision detection sensor, the load being applied to an area where the bumper reinforce and the collision detection sensor are not provided in the widthwise direction of the vehicle in the shock absorber, wherein the collision detection sensor has an interface part positioned at a first end of the collision detection sensor in a widthwise direction of the vehicle, the first end being on a side of the collision detection sensor that is on a driver side of the vehicle, wherein a length of a front bumper area in the widthwise direction of the vehicle, in which area a load applied to the front bumper is detected with the collision detection sensor, is more than or equal to a maximum distance in the widthwise direction of the vehicle between points of contact of right and left front pillars of the vehicle with a hood thereof, wherein the shock absorber is extended to cover a range longer than a range where the bumper reinforce and the collision detection sensor extend in the widthwise direction of the vehicle, and wherein the load transmission means is implemented by a lever member swingably attached to the bumper reinforce so as to transmit a displacement of a part of the shock absorber to the collision detection sensor, the part being out of contact with the collision detection sensor.
