  • Patent number: 10266143
    Abstract: The present invention provides a steering wheel. Among respective hooks of a module, the hooks being adapted to engage with wires which are disposed in respective opening portions of a steering wheel main body, an adjustment rib which is provided so as to be protrusive to an outer circumferential face of one side hook comes into contact with an inside face of one side opening portion, and restrains a position of such one side hook in such one side opening portion. An adjustment pin which is protrusively provided at a position different from that of the adjustment rib on the outer circumferential face of such one side hook elastically comes into contact with the inside face of such one side opening portion by the adjustment rib coming into contact with the inside face of such one side opening portion.

  • Patent number: 7766381
    Abstract: A steering wheel with an air bag device includes: a steering wheel body having: an annular rim portion; a boss portion; a plurality of spoke portions; an upper space; and a plurality of lower spaces. The air bag device is mounted to the steering wheel body, the air bag device includes: an air bag; an inflator; a cover member covering the air bag; and an emblem disposed at a substantially central portion of a front surface of the cover member confronting a driver's seat. The cover member includes a tear line arranged to break to form a plurality of door portions each arranged to pivot toward one of the upper and lower spaces. The tear line is formed to pivot the emblem to one of the lower spaces of the steering wheel body when the cover member is broken at the inflation of the air bag.

  • Patent number: 7703799
    Abstract: In an airbag module cover, at least one pair of tear lines is provided on a double-wall portion (an inner side wall and an outer side wall). The tear line provided on the inner side wall is formed as a slit. The tear line provided on the outer side wall is formed as a groove. Therefore, strength of the double-wall portion is reduced to tear the tear lines unfailingly and torn module cover can be opened unfailingly as a deployment door by an inflating airbag.
