  • Patent number: 7883025
    Abstract: The invention concerns a guide rail of compound type and a method of manufacturing such a guide rail. The guide rail is made like a railway rail or similar and intended for guiding interaction with a wheel of a unit travelling along the rail, comprising a long outer rail (4) made of sheet metal exhibiting the shape of a longitudinal open channel with defined inside (9) and outside (10), a long base rail (5) exhibiting a foot (1) for mounting the rail to a surface, a web (2) extending from the foot supporting a main part (3), which, in comparison to the web, is thicker and serves as a receptacle (11) for receiving and supporting the outer rail, whereby the outer rail has an outer profile that has been chosen to provide a guiding interaction with the wheel.

  • Patent number: 7591453
    Abstract: A stabilizer (1) used in a vehicle is provided by a tubular element (2) with a middle section (3) and two end sections (4a and 4b), where the end sections (4a and 4b) is bent at an angle relative the middle section (3) so that the stabilizer (1) attains a U-shape. Section surfaces perpendicular to the longitudinal/center axes (A3 and/or A4) of the tubular element at the middle section (3) and/or the end sections (4a and 4b) are of a shape where one of two vectors (V1 and V2) in the plane of a section surface is longer than the other, both vectors originating from the center of gravity of the section surface (P), extending to the periphery of the tubular element and being at an angle relative to each other. A method of manufacturing a stabilizer is also disclosed.

  • Patent number: 6751998
    Abstract: In a method for forming a three-dimensional object and in particular to a method for forming a three-dimensional beam, it is desirable to form three-dimensional beams (5) having complex forms by using an efficient forming process for the beams which may be incorporated into existing high volume production techniques. The apparatus (1, 31) for forming three-dimensional beams (5) comprises a support device and an actuation device. Support members (2, 32, 41, 51, 61) spaced about the longitudinal axis of the support device locally define an opening (4, 35, 43, 53, 63) for supporting a section of the beam (5). The position of adjacent openings (4, 35, 43, 53, 63) relative to one another defines the overall form of the beam (5) and the actuation device defines the position of each opening (4, 35, 43, 53, 63).

  • Patent number: 6726258
    Abstract: A vehicle is subjected to many requirements and wishes. One of these is that the vehicle is to protect passengers and load during a collision. This is achieved in that different parts in and on the vehicle are designed and constructed such that they, in different ways, absorb, distribute and channel energy during a collision. A bumper bar for a vehicle must be deformed both elastically and/or plastically during a collision. This invention offers a bumper bar that in its basic construction provides these properties. The invention concerns a bumper bar for vehicles where the bar is extended and has a closed cross-section with at least one forward flange (1) facing forwards in the normal direction of motion of the vehicle, an upper web (3) and a lower web (4). The forward flange (1) of the bumper bar is provided with elastically deformable grooves (6).

  • Patent number: 6471292
    Abstract: A frame (1) for a vehicle seat is intended to be deformed, in part elastically and in part plastically, under the influence of forces, for example, in connection with a collision. The frame (1) is made from a metallic, hardened material.
