摘要:
A force limiting device for a motor vehicle, which features at least two parts controlled relative to each other with a frequency-based, defined movement, wherein the parts moving relative to each other have mutually engaging gearings and the frequency-controlled movement takes place in such a way that at least one of the parts performs a wave-like advancing motion with respect to another part, in which the gearing is alternately engaged and disengaged, wherein one or a plurality of individual masses are provided, which can be coupled to or decoupled from the part performing the wave-shaped advancing movement thereby changing the force limiting characteristics of the system.

A seat belt system includes a retractor and a seat belt. The retractor includes a motor that drives a pressure rod into a seat belt such that the seat belt is nipped between the pressure rod and belt receiving portions. The driving force of the motor that controls the movement of the pressure rod is set based on the situation at the time of a collision. Thus, the load limit to be exerted on the seat belt is set flexibly and widely according to the situation in an emergency. Further, the motor and the pressure piston rod can be activated repeatedly and, therefore, can be reused.

A safety-belt arrangement for use in a motor vehicle has a safety-belt (5), one end of which is connected to a retractor (8), a sensor (11) generates a signal representative of the amount of safety-belt paid-out from the retractor. A force limiter (10) is associated with the retractor to permit safety-belt to be paid-out with a variable force limiting effect. A control arrangement (12) changes the level of force applied by the force limiter (10) in dependence upon the length of safety-belt paid-out from the retractor.

A force-limiting energy absorber comprises at least a first and a second elongated metal element (12, 13), being chosen out of a group consisting of a metal wire, a profiled metal wire, a metal strand, a bundle of untwisted metal wires and a metal rope. The elongated metal elements (12, 13) are deformable in its plastic region of its load-elongation diagram for absorbing energy. The load-elongation diagram and elongation at fracture of the first elongated metal element (12) is different from the load elongation diagram and elongation at fracture of the second elongated metal element (13).

A vehicle passenger seat active occupant restraint provides for absorbing energy from a passenger during sudden deceleration of a vehicle. The torso belt portion of a three-point restraint system is anchored using a spring and a displacement limiting linkage at the opposite end from its point of connection to the lap portion of the belt. During deceleration energy is transferred from the restrained occupant to the spring up to the displacement limit.

A safety belt roll-up mechanism is provided, and includes a force limitation device that operates in a multi-stage manner and has a two-stage torque rod and a pyrotechnically operating switching device that couples the torque rod, in various clamping lengths, with a belt shaft. The extent of the belt strap unwound from the belt shaft is utilized for actuation of the force limitation device. A ratchet wheel is connected to the belt shaft via a reduction gear mechanism. A portion of the periphery of the ratchet wheel has a toothing for engaging the reduction gear mechanism. A further portion of the periphery of the ratchet wheel has a switching contour that rests against a contact pin of an electric switch. The switching contour has a profile that effects the connection or disconnection of the switching device for the torque rod.

A seat back frame (25) includes vertical longitudinal frames (27, 29) disposed in a left position and a right position to each other, and transverse frames (31, 33) linking the longitudinal frames (27, 29) to each other, a seatbelt retractor (35) is configured to provide an emergency locking, a seatbelt (5) is linked retractably to the seatbelt retractor (35) and provided with an engagement member (23), a locking member (21) fixed to a longitudinal frame (27) and configured to disengageably lock the engagement member (23), an upper part supporter (47) is provided at an upper part (27a) of the longitudinal frame (27) and configured to support the seatbelt (5) from the seatbelt retractor (35) to return, and the seatbelt retractor (35) and the upper part supporter (49) are arranged to transmit a load acting from the seatbelt (5) on the upper part supporter (47), in a compression direction of the longitudinal frame (27).
摘要:
The present invention provides a seat belt system in which it is unnecessary to increase a distance of movement of the occupant's body by increasing a length of the seat belt to be drawn out more than it is required, so that an impact given to the occupant can be effectively reduced even in a vehicle in which an intensity of impact tends to increase. There is provided a fuse belt (5) on the lap belt (26b) located close to the anchor plate (14). When a tension, the intensity of which is higher than a predetermined value, is given to the continuous webbing (26), the lap belt (26b) is drawn out. In the retractor (10) having a clamp, there is provided an energy absorbing mechanism. When a tension, the intensity of which is higher than a predetermined value, is given, a holding force to hold the continuous webbing (26) is released and the shoulder belt (26a) is drawn out while a constant drawing force is being kept. Further, the predetermined value at which the lap belt (26b) is drawn out by the action of the fuse belt (5) is set to be lower than the predetermined value at which the shoulder belt (26a) is drawn out by the energy absorbing mechanism of the retractor (10).
摘要:
A webbing retractor is provided with a lock mechanism. The webbing retractor further comprises a bobbin, a webbing-holding member and a webbing. The bobbin has a drum portion and a pair of flanges arranged on opposite ends of the drum. The flanges define grooves formed in a mutually-opposing relationship and angularly extending over a predetermined length in a webbing-releasing direction as a first direction of rotation. The webbing-holding member extends between the grooves. The webbing is secured at one end thereof in the bobbin, wound back about the webbing-holding member at a first portion thereof apart from the one end thereof toward an opposite end thereof, and then wound in layers around the drum portion in the first direction of rotation at a second portion thereof closer to the opposite end than the first portion.
