A device for visually setting the spring force of a seat suspension for use in an automotive seat according to the weight of an occupant of the seat includes a display section formed of a light reflecting body and disposed on an inside lining of an automotive door for indicating the proper height of the automotive seat, and a visually confirming function section disposed in the seat for enabling the seat occupant to visually confirm the above-mentioned display section when the height of the seat is set at a predetermined level by adjustment of the spring force of the seat suspension. When the spring force of the seat suspension is properly set and thus the height of the seat is set at a predetermined level, the visually confirming function section enables the occupant while remaining seated to visually confirm the display section located in the door lining at a position where the occupant can easily observe it.

A method of producing a decorative movement of metal particle display in a pool of molten wax of a burning candle. Portions of a wax crayon containing colored metallic particles different from the color of the candle wax is melted in the flame of the candle and directed to fall into the molten pool for observation.
摘要:
A backlighted button or knob made by multi-shot molding has a translucent part and an opaque part. At the front of the button the translucent part contains a ridge shaped in the form of a symbol which is illuminated. The opaque part surrounds the ridge to mask light to surrounding areas. Where the symbol is a closed figure defining an island, a passage behind the ridge coupled the island to the surrounding areas to allow opaque material to flow to the island during molding, and results in an opaque bridge in the passage. To minimize a shadow of the bridge on the illuminated symbol the bridge is spaced far behind the ridge to allow light to be conducted through the translucent material to the ridge portion just in front of the bridge.
摘要:
A pointer for use in an instrument panel, such as a speedometer, in a vehicle. According to one embodiment, the pointer includes a conically shaped pointer body to which a pointer base is secured. A light source is disposed within the pointer base and a slit is provided in the body. The inner surface of the pointer body is reflective such that light directed from the light source is reflected off of the reflective surface and through the slit. In another embodiment the light source is disposed externally of the pointer and a reflecting member is provided in the pointer for reflecting the light towards the distal end of the conical body. The reflecting member can include a reflecting mirror or, alternatively, a prism.
