[0043] [1. Structure]

[0044] First, description will now be made regarding the peripheral structure of the anti-underrunning protection device according to the first embodiment.

[0045] like figure 1 As shown, the underrun protection device 10 is attached to the lower portion of the front portion 1a of the vehicle frame 1 so that the longitudinal sides of the underrun protection device 10 extend in the width direction of the vehicle. The underrun protection device 10 is connected to a plurality of brackets 5 , 5 formed on the left and right portions of the front portion 1 a of the vehicle frame 1 , respectively.

[0046] [1-1. Peripheral structure]

[0047] Hereinafter, the structures of the vehicle frame 1 and the bracket 5 will now be sequentially described.

[0048] [1-1-1. Frame]

[0049] The frame 1 of the vehicle is a so-called trapezoidal frame and includes a pair of side frames (longitudinal members) 2 , 2 and a cross member (cross member) 3 .

[0050]The side ...

Abstract

A structure for an underrun protector is provided, which enables weight to be suppressed, and with which strength and rigidity are ensured. This structure for an underrun protector (10) to be attached to left and right brackets on a front section or a rear section of a vehicle-body frame of a vehicle is configured so as to be provided with an outer surface section in a front-rear direction of the vehicle, an inner surface section in the front-rear direction of the vehicle, an upper surface section, and a lower surface section, and so as to have a hollow closed cross section. Weight-reduction holes (51, 52, 53) are formed in the upper surface section and / or the lower surface section of the underrun protector (10).

Description

technical field [0001] The present invention relates to a structure of an anti-underrun protection device which inhibits a vehicle of a lower height from penetrating under another vehicle of a higher height in the event of a collision between vehicles. Background technique [0002] In order to restrain a vehicle with a lower height (eg, a passenger car or a minicar) from digging under the front part or the rear part of a vehicle with a higher height (eg, a motor truck), a front part mounted on the frame is equipped with Or vehicles with higher heights of anti-underrun protection under the rear section have been put into practical use. [0003] An underrun protection device needs at least sufficient strength and rigidity to inhibit another vehicle from getting under the vehicle on which the underrun protection device is installed. Unfortunately, anti-underrun protections formed of steel, which have been widely used in vehicles, result in an increase in the weight of the vehi...
