Embodiment Construction

[0040] figure 1 and 2 A possible embodiment of a molded part 1 is shown schematically, which serves to transmit crash forces to a hood sensor and which can be used, for example, in a motor vehicle. figure 1 The molded part 1 is shown from a rear perspective. figure 2 The molded part 1 is shown from a frontal perspective. The molded part 1 together with the cover sensor 100 forms a structural unit, wherein the cover sensor 100 is connected to the molded part 1 .

[0041] The molded part 1 has a receiving region 2 for absorbing the impact force and a transmission section 3 for transmitting at least part of the impact force to the cover sensor 100 . The molded part 1 is, for example, an injection-molded plastic part.

[0042] The profiled part 1 is preferably designed as an elongated profile with an approximately C-shaped cross section, the receiving area 2 being arranged at the open end of the profile and the transmission section 3 being arranged at the other end of the pro...

Abstract

A hood sensor assembly of a motor vehicle includes a molding for transmitting an impact force to a hood sensor. The molding includes an absorption area for absorbing an impact force and a transmission section for transmitting at least a portion of the impact force to a hood sensor. An elastically movable material section provides a restoring force against which the molding can be arranged in its installation position (E). The hood sensor is supported within the molding.

Description

technical field [0001] The invention relates to a molded part of a motor vehicle for transmitting crash forces to a hood sensor, having a receiving region for absorbing the crash forces and a transmission section for transmitting at least part of the crash forces to the hood sensor. Background technique [0002] Such molded parts are used, for example, in motor vehicles and cooperate with hood sensors. The molded part is used to transmit the impact force to the cover sensor. In the event of a collision between a vehicle and a pedestrian, the energy of the collision force acts via the profiled part on the hood sensor, which is triggered by this mechanical load, causing the hood of the vehicle to pop up. This bouncing of the vehicle hood is known as a so-called active hood and is a protective measure to reduce the amount of damage to the pedestrian, especially the head, when the vehicle hits the pedestrian. [0003] The hood sensor is usually implemented in an absorbing stru...
