Abstract: The invention relates to a method for the manufacture of a part of a structural component of a vehicle, intended to be connected by spot welding to a second part, starting from a coated steel plate and of a thickness of 1-3 mm, which comprises subjecting the plate to hot stamping, subsequently subjecting at least one localized and previously selected zone of the first part to a heat treatment, irradiating it with a diode laser beam of a power comprised between 500 W and 6 kW until reaching a temperature comprised between 400-900 °C, then leaving it to cool to change its microstructure, providing said zone with an intentionally lower martensite content and accordingly with a lower strength and greater elongation in comparison with those of its adjacent zones that have not been heat treated.

Abstract: The invention relates to a method for the manufacture of a structural component of a vehicle, starting from a HSS or UHSS steel plate with a protective coating. The method comprises the operation of subjecting the plate to a prior hot stamping formation, followed by a subsequent operation of subjecting at least one localized and previously selected zone (Z) of the hot stamped plate to a subsequent heat treatment, irradiating it with a diode laser beam of a power comprised between 500 W - 6 kW until reaching a temperature between 400-900 °C, then leaving it to cool at room temperature or at a controlled cooling rate equal to or less than 10 °C/s to change its microstructure, providing said localized zone with an intentionally lower martensite content and a lower yield strength and greater elongation in comparison with those of its adjacent zones not subjected to said heat treatment.

Abstract: The invention relates to a shock absorbing system applicable to the bumper of a vehicle comprising a shock absorber with a deformable tube joined at one of its ends to the element of the vehicle which acts as a bumper, and a retaining device of the absorber comprising a mechanism susceptible to adopting at least one blocking position and one releasing position in which it prevents and allows, respectively, the displacement of a retaining portion of the absorber in an axial direction. The aforementioned mechanism comprises two rotating retaining connecting rods in a plane perpendicular to the longitudinal axis of the deformable tube, connected to a common support and linked to one another such that the rotation of any one of the connecting rods is transmitted to the other to achieve a similar movement but in the opposite direction; and an electromechanical transducer connected to the retaining connecting rods for the purpose of transmitting to them, when a predetermined electrical signal is received, an impulse sufficient to displace them such that the mechanism goes from adopting a blocking position to a releasing position almost instantaneously.
