An interior trim component such as a vehicle dashboard includes a substantially rigid and form-stable substrate of polypropylene and natural fibers, a supporting halo skeleton and other frame components heat fused onto the backside of the substrate, and a polyolefin foam layer as well as a decorative polyolefin cover film laminated onto the front side of the substrate. The foam layer has an increased thickness and a decreased foam density at sharply contoured or curved areas of the trim component, in comparison to the flat surfacial areas. As a result, the trim component has a desirable soft-touch characteristic and impact absorbing properties at all areas including protruding curves and edges. A method for forming such a trim component involves steps of pre-molding the foam layer and cover film by vacuum thermoforming, pre-molding the substrate by vacuum thermoforming, and then heat laminating the pre-heated, pre-molded substrate onto the pre-molded foam layer and cover film. The sharply curved or contoured areas of the component are provided with a greater tolerance spacing between the substrate and the cover film, which are held to the respective mold contours by vacuum. Under the effect of heat and the applied vacuum, the foam layer expands to have a greater thickness and a lower density in these sharply contoured areas.

A wave gear device has a rigid internal gear, a flexible external gear, and a wave generator. The tooth profiles of both gears are initially defined by a basic rack tooth profile shape. The lower parts of the dedendum portions of these tooth profiles are modified by curves C2 and C3 having pressure angles α2 and α3 that are less than the standard pressure angle α1 of the basic rack tooth profile shape C1. An increase in thickness of the tooth bottom side can be minimized even if the tooth depth is increased and the tooth thickness / tooth space ratio changed to increase the tooth thickness. Hence, the ratcheting torque of a wave gear device having a high reduction gear ratio can be increased without reducing the service life and strength of a pinion cutter for the rigid internal gear, or the fatigue strength of the flexible external gear.
