<p><P>PROBLEM TO BE SOLVED: To provide a pre-crash seat belt device which is short till tension is generated in a webbing and has a high restriction performance. <P>SOLUTION: This pre-crash seat belt device 100 has a differential gear 110. This device includes a ring gear 150 rotating by receiving input from a motor 120, a differential case 160 rotating by interlocking with the ring gear, two pinion gears 170 and 180 oppositely arranged in the differential case, two side gears 190 and 200 meshing with the two pinion gears, an interlocking gear 210 rotating by interlocking with the first side gear 190, a rotation regulating means 220 for regulating the rotation of the interlocking gear and releasing the rotation regulation of the interlocking gear when torque applied to the interlocking gear from the first side gear exceeds a predetermined value, and one-way clutches 282 and 284 for preventing the reverse rotation of the two pinion gears. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
