Date Jan. 11, 1996Spring strut for a front wheel suspension arrangement of the McPherson type for motor vehicles, which spring strut (1) presents a link bracket (40) for a stabilizer link intended to be pivotably arranged on the spring strut of a stabilizer forming part of the vehicle's front wheel suspension. The link presents a pivot portion (38) with an attachment means (39) for mounting the link on an attachment point on the link bracket. With respect to its attachment point, the link bracket (40) is oriented to adopt a fixed angular position in relation to the angular position for the wheel axis of the wheel axle, as determined by the carrier for the wheel axle. The angular position is the same for both spring struts in the vehicle's front suspension with respect to a turning angle about the longitudinal axis of the spring strut in relation to the wheel axis. Furthermore, the angular position deviates from 180 DEG  by an angular deviation (v) which is identical for both left and right spring strut, as viewed clockwise for both spring struts. The angular deviation is chosen so that the pivot portion of the stabilizer is positioned symmetrically on both sides of the vehicle, and essentially directed opposed to the axis direction of the wheel axle.

Abstract: On moving forwards a coupling component (34) enters into engagement between the towing frame (30) and a load support (18) movable in front of it on a vehicle frame (1, 2, 4). On moving backwards from the loading position by the towing frame, the load support is picked up with the aid of the coupling component. When the front load support in this movement reaches its position in the vehicle longitudinal direction, the coupling component is automatically freed so that the load support remains in the correct position, whilst the towing frame moves backwards to its rear position. The freeing movement can be produced by a stop component (62) on the vehicle frame (2), which directly activates the coupling component when it passes.

Abstract: The invention presented here relates to a method for detecting the presence of objects by means of an optical sensor in a scene within the sensor's field of view. The sensor is made record images of the scene so that each individual image element is assigned a value corresponding to the detected heat radiation within the infrared wavelength range. The method is characterised in that the sensor records (1, 2) at least a pair of consecutive images of the scene, where one of the images in each pair is recorded (2) under illumination of the scene by means of a radiation source. Thereafter, a comparison image is created (4) such that each image element in the comparison image is assigned a value corresponding chiefly to a differential or quotient between the radiation values for corresponding image elements in the images recorded (2) under illumination, and the radiation values for corresponding image elements in the images recorded (1) without illumination. The image elements of the created comparison image are scanned, and the image element values that exceed a certain threshold level are marked (5) as an optical aperture within the infrared wavelength range. The invention also comprises a device for executing the method above.
