    Abstract: The objective is to suppress function impairment of a detection device during a light collision. A vehicle front structure includes a bumper reinforcement, a bracket, and a detection device. The bumper reinforcement extends in a vehicle-width direction at a front part of the vehicle. The bracket is attached to an end in the vehicle-width direction of a front part of the vehicle. The detection device is attached to the bracket, and detects objects obliquely ahead of the vehicle. An end on the vehicle-width direction inside of the detection device is located more to the vehicle-width direction inside than an end on the vehicle-width direction outside of the bumper reinforcement.

    Abstract: A deformation structure has at least a first layer and a second layer, which are spaced apart from each other and are mounted to be movable relative to each other in the deformation direction or load direction. The first layer and the second layer have complementary protrusions and recesses, which are designed such that the protrusions of the first layer can dip into the recesses of the second layer and vice versa. The first layer and the second layer are connected to each other by deformable connecting pieces such that, in the event of a high impulse in the deformation direction, the protrusions of the first layer dip into the recesses of the second layer and the protrusions of the second layer dip into the recesses of the first layer such that the deformation structure is deformed in the deformation direction at a relatively low level of force and, in the event of a low impulse in the deformation direction, the protrusions of the first layer hit the protrusions of the second layer such that the deformation structure is deformed further in the deformation direction at a relatively high level of force. The deformation control device is formed or produced separately from the first and the second layer and is removably or non-removably connected to the first layer and the second layer.

    Abstract: An automotive crashworthiness energy absorption part provided at a front part or a rear part of an automotive body and absorbing crashworthiness energy by undergoing axial crush when receiving input of a crashworthiness load from a front or a rear of the automotive body includes: a tubular member configured to absorb crashworthiness energy by undergoing axial crush, the tubular member including a top portion and side wall portions continuous with the top portion; and resin coated or patched on first outer surfaces including at least outer surfaces of the top portion and the side wall portions of the tubular member. The coated or patched resin has a thickness of 8 mm or less after being heated, forms at least part of a peripheral wall portion of a closed cross section space, and is bonded to the first outer surfaces with an adhesive strength of 10 MPa or more.

    Abstract: The present invention relates to extrusions for structural components, such as bumper, side impact beam, seat sill in vehicles and more particularly to a method for optimizing strength and energy absorption of 6XXX aluminium alloys extrusions by variations in thermomechanical ageing (TMA) consisting in



    i) an artificial preageing treatment with a duration t1 at a temperature T1 selected to increase the yield strength of said extrusion between 5% and 20%, said temperature T1 being typically between 120° C. and 180° C. and said duration t1 being typically between 1 and 100 hours, to obtain an artificially preaged extrusion,
    ii) a plastic deformation of said artificially preaged extrusion between 1% and 80% to obtain a deformed extrusion,
    iii) a final artificial ageing treatment of said deformed extrusion with a duration t2 at a temperature T2, said temperature T2 being typically between 140° C. and 200° C. and said the duration t2 being typically between 1 and 100 hours.

    Abstract: A vehicle front compartment structure and a vehicle. The vehicle front compartment structure includes a front anti-collision beam, a front longitudinal beam, an upper side beam, and an energy-absorbing box. A side of the energy-absorbing box is connected to the front anti-collision beam. The front longitudinal beam and the upper side beam are separately connected to another side of the energy-absorbing box. A first force transmission structure is formed through the front anti-collision beam, the energy-absorbing box, and the upper side beam. A second force transmission structure is formed through the front anti-collision beam, the energy-absorbing box, and the front longitudinal beam.
