Abstract: A seat belt device includes a spindle (11) for retracting a seat belt (13), an electric actuator (55), a pre-tensioner (14) and a power transmission mechanism (20), wherein the power transmission mechanism (20) can reversibly switch the connection and disconnection between the electric actuator (55) and the spindle (11) before the pre-tensioner (14) is activated, while when the pre-tensioner (14) is activated. The power transmission mechanism (20) non-reversibly interrupts the connection between the electric actuator (55) and the spindle (11) via an elastic piece (60) when a torque difference between an actuator-side gear (80) and a spindle-side gear (82) becomes larger than a predetermined value.

Abstract: A seatbelt device for a vehicle. The seatbelt device includes a seatbelt connected at a first end to retractor and connected at a second end to a belt position changing member, which is movable between forward and rearward positions relative to the vehicle. The second end of the seatbelt is connected to the belt position changing member such that the position of the second end of the seatbelt changes relative to the belt position changing member, as the belt position changing member is moved from the rearward position to the forward position, thereby preventing the webbing of the seatbelt from twisting and inverting of the tongue plate upon activation of the belt position changing member, the latter which makes the tongue the plate difficult for an occupant to reach.

Abstract: A power transmission mechanism (19) for transmitting power from a motor (34) to a spindle (12) having a clutch housing (50), a pawl (41) engageable with the clutch housing (50), a gear wheel (57) which holds the pawl (41) and rotates with the rotation of the motor (34), an outer gear cover (26), and a friction ring (42) engaging with the pawl (41) and held on the outer gear cover (26) by frictional force. The friction ring (42) is provided with a protruding portion (42a) which engages with an engagement groove (41b) of the pawl (41), and a plurality of contact pieces (42b) in contact with an outer peripheral surface of a small diameter ring portion (26c) of the outer gear cover (26) and press radially against the outer peripheral surface towards an inner side The friction ring can be easily coupled to the outer gear cover.
