[0058] First refer to figure 1 and figure 2 , a leg sweeper as a pedestrian protection device constructed according to the first embodiment of the present invention will be explained. exist figure 1 and figure 2 The leg-sweeping device generally represented by 10 is installed to the inside of the front bumper provided by the cowl of the car. Such as figure 1 and figure 2 As shown, the leg sweeping device 10 includes a base plate 12 as a plate member.

[0059] The substrate 12 is formed of a synthetic resin material such as polypropylene or ABS resin, and is constituted by a thin flat plate having a substantially rectangular shape. In the base plate 12, when the leg sweeping device 10 is installed on the vehicle, figure 1 The dimension measured in the direction extending in the left-right direction, that is, the dimension measured in the vehicle width direction or the vehicle left-right (lateral) direction, is made smaller than the vehicle width by an appropriate amou...

Embodiment 1

[0101] For further clarification, an example will be explained with respect to the first embodiment. It should be understood that the invention is not limited to the details of this example. First, it is prepared by implementing a casting mold using polypropylene Figure 1-3 The leg sweeping device shown. In the leg sweeping device, each rib has a height of 10-15 mm and a width of 10-15 mm. And, the radius of curvature R of the curved connecting portion constituted by the connecting portion between the rib end of each rib and the flat portion of the substrate 1 The radius of curvature R of the curved boundary portion formed by the boundary portion between the protruding portion of the rib and the end of the rib is 12mm 2 20mm. The leg sweeping device 10 thus prepared was used as the device of the present invention.

[0102] For comparison, unlike the device of the present invention described above, a leg sweeping device having a structure similar to that disclosed in Pate...

[0108] Refer below Figure 8 and Figure 9 , to explain the leg sweeping device as a pedestrian protection device constructed according to the second embodiment of the present invention. exist Figure 8 and Figure 9 The leg sweeping device, generally indicated at 110, is mounted to the inside of the front bumper of the vehicle's cowl, like the leg sweeping device 10 described in the first embodiment. Such as Figure 8 and Figure 9 As shown, the leg sweeping device 110 includes a base plate 112 as a plate member.

[0109] The substrate 112 is formed of a synthetic resin material such as polypropylene or ABS resin, and is constituted by a thin flat plate having a substantially rectangular shape. In the base plate 112, when the leg sweeping device 110 is installed on the vehicle, Figure 8 The dimension measured in the direction extending in the left-right direction, that is, the dimension measured in the vehicle width direction or the vehicle left-right (lateral) direct...

Abstract

A pedestrian protection for a vehicle comprises the following component: a plate component: the plate component is arranged under the vehicle front part, extends in the front and back direction and comprises a front part and a back part which is fixed on the vehicle; at least one reinforced bar: each reinforced bar is wholly arranged in the front part of the plate component and comprises a bar extending-out part and a bar terminal part, the extending-out part extends in the front and back direction of the vehicle and is provided with groove structures opening upwards or downwards, and the bar terminal part is provided with a plate structure, extends wholly from the back edge of the bar extending-out part and is used for connecting the back edge of the bar extending-out part and the bak of the plate component. The pedestrian protection for a vehicle can be used for protecting the legs of pedestrians owing that when the front terminal of the plate component contacts the legs of pedestrians, the legs of pedestrians contacting the front of the vehicle can be made to be away, thus protecting the legs of pedestrians; wherein, the pedestrian protection also comprises at least one first secondary reinforced bar, and the width of each first secondary reinforced bar is less than the width of each reinforced bar in the at least one first secondary reinforced bar; each first secondary reinforced bar extends continuously in the front and back direction of the vehicle through one bar terminal part of a reinforced bar in the at least one first secondary reinforced bar and the front lateral part of the plate component back part.

Description

[0001] This application is based on Japanese Patent Applications No. 2006-164270 and No. 2006-164271 filed on June 14, 2006, the contents of which are incorporated herein by reference. technical field [0002] The present invention generally relates to a pedestrian protection device for a vehicle, and in particular relates to an improved structure of a pedestrian protection device which is arranged at the lower part of the front wall of the vehicle and is arranged to The lower part of the pedestrian's leg is contacted to sweep away the lower part of the pedestrian's leg, thereby protecting the pedestrian's leg. Background technique [0003] Various types of protectors are generally installed on the front wall, rear wall or side wall of a vehicle such as an automobile for absorbing impact energy generated in a collision, thereby protecting the vehicle body and occupants in the vehicle. In recent years, a device has been provided on the cowl of a vehicle for protecting the ped...
