    Abstract: A hole plug includes a head portion and a foot portion projecting from a back surface of the head portion to be inserted into a hole to be blocked. The foot portion has a cylindrical shape formed of several uprising plates extending from the back surface of the head portion. An engaging step portion is formed at a base end of each uprising plate for holding a rim of the hole to be blocked together with the head portion. A supporting device is formed at an inside of each uprising plate for limiting bending of each uprising plate inwardly in the radial direction.
    Type: Grant

  • Patent number: 6564433
    Abstract: A clip for attaching a cover member to cover a groove section includes a base plate attached to a bottom surface of the groove section, a pair of engaging sections projected from the base plate and engaging side engaging sections of the cover member, and an abutting piece section projected from the base plate and having a free end abutting against an inner surface of the cover member to restrain an excessive movement thereof. In the condition that the cover member is attached, a spring force of the free end is applied to the cover member so that friction between the cover member and the engaging sections of the clip at both sides of the trim is effectively increased. Accordingly, the trim can be held in the width direction without loosening.

  • Patent number: 6431584
    Abstract: The holding device for use in mounting a garnish on a front pillar has a pin member at the side of the garnish and a grommet member at the side of the front pillar. A leg portion of the pin member is inserted into a cylindrical portion of the grommet member. The leg portion has a first mounting engagement claw that is engaged with a first engagement portion of the cylindrical portion to hold the garnish in a given mounted state. The engagement of the first mounting engagement claw with the first engagement portion is released by means of expansion pressure of an air bag apparatus, while a second mounting engagement claw of the leg portion is brought into engagement with a second engagement portion of the cylindrical portion to prevent the pin member from coming off. At this time, a clearance is formed between the garnish and the front pillar, thereby developing an air bag into a cabin compartment of the vehicle through the clearance.
