Embodiment Construction

[0040] figure 1 with 2 A possible embodiment of the molded part 1 is shown in a schematic diagram, which serves to transmit impact forces to a cover sensor and can be used, for example, in a motor vehicle. figure 1 The molded part 1 is shown from the rear view. figure 2 The molded part 1 is shown from the front perspective. The molded part 1 and the cover sensor 100 form a structural unit, wherein the cover sensor 100 is connected to the molded part 1.

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

[0042] The molded part 1 is preferably designed as an elongated profile with a substantially C-shaped cross-section, wherein the receiving area 2 is arranged at the open end of the profile and the transmission section 3 is arranged at the other end of the profile. The molded pa...

Abstract

The invention relates to a molded part (1; 1') of a motor vehicle for transmitting crash forces to a cover sensor (100), which has a receiving area (2) for absorbing the crash forces and for directing at least a part of the crash force Transmission section (3) for force transmission to the cover sensor (100). In which at least one elastically movable material section (4) is provided, the molded part (1) can be accommodated in the installation position (E) against the restoring force of the material section. The invention also relates to a structural unit having such a profiled part (1') and a cover sensor (100). Furthermore, the invention relates to a device in a motor vehicle, a molded part (1') and a structural unit with a cover sensor (100).

Description

Technical field [0001] The present invention relates to a molded part of an automobile for transmitting a collision force to a cover sensor, which has a bearing area for bearing the collision force and a transmission section for transmitting at least a part of the collision force to the cover sensor. Background technique [0002] Such molded parts are used, for example, in automobiles and cooperate with cover sensors. The molded part is used to transmit the impact force to the cover sensor. In a collision between a car and a pedestrian, the energy of the collision force acts on the cover sensor through the molded part, which is triggered by this mechanical load, which causes the cover of the car to bounce. This pop-up of the car cover is called a so-called active cover and is a protective measure for reducing the damage value to the pedestrian, especially the head, when the car collides with the pedestrian. [0003] The cover sensor is usually implemented in an absorbing structur...
