Abstract: A cover assembly has a support defining a pivot axis, a cover pivotal relative to the support about the pivot axis between an open position and a closed position, and a torque spring having first and second ends, a biasing coil part from which the first end extends, and a gripping coil part extending from the biasing coil part and from which the second end extends. The first end is seated in the cover, and the gripping coil part, except when is installed or adjusted, frictionally tightly and elastically engages the support and nonrotatably secures the second end to the support against rotation relative to the pivot axis. The gripping coil part is elastically deformable during installation or adjustment to disengage from the support and allow angular or axial movement of the gripping coil part and repositioning on the support.

Abstract: The invention relates to a motor-vehicle accessory, comprising a first part and at least one second part pivotal about an axis (a) relative to the first part in at least one bearing assembly (20a, 20b), and the bearing assembly (20a, 20b) comprises a bearing pin (14) on which a bearing sleeve (22) is coaxial to the bearing axis (a), and the bearing pin (14) forms a head (19) with an axial retaining face (30). The particularity is that of the bearing pin (14) having first coupling formation that engages in a second coupling formation of the bearing sleeve (22) and prevents relative rotation in a pivot direction (u1, u2) between the bearing sleeve (22) and the bearing pin (14).

Abstract: Valve gap measuring device for measuring an axial gap between a valve seat ring of an internal combustion engine which is pressed into a blind through bore, and the base of the blind through bore, has an imaging optical system for imaging the gap at at least one circumferential location on the borehole. The imaging optical system is in image transmission connection with a digital image sensor and a digital evaluation apparatus situated downstream from the image sensor. The evaluation apparatus is configured for determining the gap width, based on the image recorded by the image sensor.

Abstract: A motor-vehicle headrest has a base fixable to a motor vehicle seat and a cushion support having a forwardly directed front face adapted to engage a head of a person in the seat. An upper link has a front end pivoted at an upper support axis on the support and a rear end pivoted at an upper base axis on the base, and a lower link having a front end pivoted at a lower support axis on the support offset downward from the upper support axis and a rear end pivoted at a lower base axis on the base offset downward from the upper base axis. The cushion is shiftable relative to the base between a rear position and a front position on pivoting of the links about the respective axes. A rigid brace is pivoted on the upper link between the upper axes and on the lower link between the lower axes.

Abstract: In a crankshaft testing method for the classification testing of at least one bearing surface of a crankshaft or the like, a reflection of a reference object at the bearing surface to be tested (reflection image) is detected by at least one sensor, using a sensor system. The detected reflection image is evaluated with regard to its contrast, and the crankshaft is classified as “unsatisfactory” when the contrast is below a predefined or predefinable threshold value.

Abstract: A method for characterizing a flue gas burnout quality of a combustion process in a combustion system having a gas burnout zone includes optically detecting in a visible wavelength range, in a flow cross section of the gas burnout zone, low-soot combustion regions, regions without combustion, and sooting regions, so as to provide a plurality of successive individual images, the regions without combustion and the sooting regions having different dynamics. The plurality of successive individual images are analyzed so as to distinguish regions of transition, to the low-soot combustion regions, of the regions without combustion and the sooting regions.

Abstract: An apparatus for imaging the inner surface of a cavity in a workpiece has an optical system including a panoramic field of view that is linked to an imager and a downstream evaluation device by an image communication link. The apparatus furthermore has an illumination system including a light source to illuminate an imaging region of the inner surface, which region has been captured by the optical system. According to the invention, the illumination system is disposed in such a way relative to optical system, and for which the beam path is selected in such a way, that a first axial section of the imaging region is able to be illuminated under brightfield illumination, while simultaneously a second axial region spaced apart from the first axial region is able to be illuminated under darkfield illumination.

Abstract: The invention relates to a headrest (10) for a vehicle seat, comprising a central part (11) containing a cushion support and a cushion that is held on top of a seat back by means of at least one support rod, the front region of said headrest having a head support region (17). The cushion support is optionally pivotally mounted about a horizontal pivoting axis (x). A respective lateral part (12) is pivotally mounted on each side of the head support region (17), about a displacement axis (y), which extends respectively in a lateral direction in relation to the central part (11) and which is located in the upper region of the central part (11). The displacement axis (y) extends obliquely at a first angle (a) to the pivoting axis (x) and to a horizontal projection plane that is common to the pivoting axis (x) and backwards (h) in relation to the head support region (17), the displacement axis (y) being situated on a horizontal plane that runs parallel to the pivoting axis (x).
