  • Publication number: 20230060152
    Abstract: A vehicle is disclosed that includes: a grille supporting a functional accessory; a bumper beam that is located (positioned) axially inward of the grille; and a first energy absorber that is connected to the bumper beam. The first energy absorber defines a cavity that is configured to accommodate inward axial displacement of the grille resulting from a low-force impact between the vehicle and an external object to thereby inhibit damage to the functional accessory.

  • Patent number: 11511691
    Abstract: A vehicle includes: a bumper assembly defining opposite lateral ends and an overall width extending therebetween, the bumper assembly defining a recessed area located between the opposite lateral ends thereof; an electronic sensor supported by the bumper assembly in cantilevered relation; and an energy absorber positioned within the recessed area to protect the electronic sensor and reduce dislocation of the electronic sensor by absorbing energy resulting from an impact between the vehicle and an external object. The energy absorber defines opposite lateral ends and an overall width extending therebetween less than that the overall width of the bumper assembly such that the opposite lateral ends of the energy absorber are spaced inwardly from the opposite lateral ends of the bumper assembly.

  • Patent number: 10850697
    Abstract: A vehicle includes: a bumper beam; an electronic sensor that is fixed in relation to the bumper beam; and an energy absorber that is connected to the bumper beam in general alignment with the electronic sensor. The energy absorber is configured and positioned to protect the electronic sensor and reduce dislocation of the electronic sensor by absorbing energy resulting from a low-force impact between the vehicle and an external object (e.g., another vehicle). The energy absorber may be provided in the front and/or rear-ends of the vehicle, and, in certain embodiments, may be connected to an end face of the bumper beam (e.g., to a front face or a rear face of the bumper beam) such that the energy absorber is positioned outwardly (e.g., forwardly or rearwardly) of the electronic sensor along a length of the vehicle.
