Abstract: Provided is a seatbelt device which prevents an occupant from hitting his face against an airbag deploying at the time of a vehicle collision. In order to take up any seatbelt slack before a collision and prevent the occupant from being displaced forward, the seatbelt device comprises a first tension modifier for winding the seatbelt and taking up the seatbelt slack when a collision is predicted, and a second tension modifier for further enhancing the tension of the seatbelt and securing the occupant to the seat at the time of such collision, thereby ensuring that the occupant does not exist in the airbag deployment zone when the airbag is activated.

Abstract: An automotive passenger restraint and protection apparatus includes an electric retractor having a motor for retracting and protracting a seatbealt. The apparatus also includes an airbag driving device, a pretensioner, a speed detecting device, and a controller. The controller controls at least one of the actuation time or expansion pressure of an airbag by the airbag driving device, actuation time of the pretensioner, a force of the pretensioner for retracting the seatbelt, and a force of the seatbelt driving device for retracting the seatbelt, based upon the speed of protraction of the seatbelt. The controller controls the airbag driving device to shorten the actuation time of the airbag when the speed of protraction of the seatbelt is greater than a predetermined value, and prolongs the actuation time of the airbag when the detected speed of protraction of the seatbelt is lower than the predetermined value.

Abstract: An automotive passenger restraint and protection apparatus prevents damage to a seatbelt. An electric retractor having a motor for retracting and protracting the seatbelt includes the automotive passenger restraint and protection apparatus. The motor is controlled by a CPU. The CPU detects whether the seatbelt is attached to, or disconnected from, the occupant, and whether the seatbelt has been retracted to a limit thereof. The motor is controlled by the CPU such that when the CPU detects that the seatbelt is retracted and when the CPU subsequently detects that the seatbelt has been fully retracted to the limit thereof, the seatbelt is prevented from being further retracted.

Abstract: There is provided a seat belt apparatus which not only can reduce the possibility that an end lock phenomenon can occur when removing the mounting of a webbing but also, even in case where the end lock phenomenon occurs, can remove the end lock phenomenon easily. That is, in a seat belt apparatus including a seat belt retractor having a lock mechanism structured such that, when the acceleration of a vehicle body or the pay-out acceleration of a webbing is a predetermined value or more, a pawl member (15) is engaged with a pawl wheel (13) to lock the rotation of a bobbin (2) with the webbing wound thereon in the webbing pay-out direction, the pawl wheel (13) is structured such that two or more kinds of ratchet teeth (T1) and (T2) differing in addendum circle diameter are mixedly arranged in the peripheral direction of the pawl wheel according to a predetermined manner, thereby being able to lower the probability of the webbing end lock occurring.
