Abstract: The improved installation tool for installing grommets in a hole in a panel having a countersink end includes an anvil having a convex surface for contacting the head of the grommet after the grommet is installed in the hole. A flaring die having a tapered tubular portion for inserting into the grommet is mounted on the open end there in and chamfered surface for deforming the end of the grommet so that it is deformed into the countersink. This is accomplished by a threaded rod that extends through a hole in the anvil, grommet and threadably engages internal threads in the die. Withdrawing of the rod causes the die to be moved against the grommet and flares the end of the grommet into the countersink and locks it in place.

Abstract: The invention is a non contact laser inspection self centering device to inspect the counter sink portion of a counter sunk fastener hole on a surface. In detail, the self centering and seating device includes a combination laser transmitter and receiver for transmitting a laser bean across a surface and for receiving the return signal from the surface. A self centering device is attached to the combination laser transmitter and receiver for aligning the laser transmitter with the fastener hole such that the transmitted and received laser beam passes across the center of the counter sink portion of the fastener hole. A computer system is connected to the combination laser transmitter and receiver for analyzing the transmitted and returned laser signal from the surface and determining if the counter sink portion of the hole is within tolerance.

Abstract: The invention relates to a roller blind arrangement, in particular for use in a vehicle, with a winding shaft (10) which extends in a main direction of extent (2), is in the form of a hollow tube and is intended for receiving an unwindable flexible sheetlike structure, a winding spring (12) which is inserted into the winding shaft (10), is designed as a helical spring and extends in the main direction of extent, and a damping profile (20) which extends in the main direction of extent (2) and is arranged in an annular space (16) between the winding shaft (10) and the winding spring (12). According to the invention, the damping profile (20) is designed in such a manner that it bears with outer contact sections (24) against an inner side of the winding shaft (10) and with inner contact sections (22) against an outer side of the winding spring (12). Use, in particular roller blind arrangements in vehicles, for example for coverings of the boot.
