摘要： Force limitation in retractors is needed to avoid injury to an occupant from the seat belt itself particularly at high crash impact loads. The invention provides a seat belt retractor comprising a spool including force limiting means for allowing further payout of the seat belt webbing after the spool has locked, under the influence of an occupant's forward momentum in the crash condition. In one aspect the force limiting means is provided by a plurality of fins provided on the outer surface of the spool, each fin having a section which extends in a generally radial direction and a section which extends circumferentially, the circumferentially extending section of one fin overlapping the circumferentially extending section of an adjacent fin and supported by the radial extending section of that adjacent fin, so that a force tending to tighten the webbing on the spool, acts in a direction to crush the radial sections of the fins and to slide the circumferential sections over each other, thus reducing the effective outer circumference of the spool. In another aspect the force limiting means comprises an energy absorbing member connecting the spool to the spool shaft, the connection being rigid below a predetermined force, and above the predetermined force there being relative rotation of the spool with respect to the spool shaft to allow pay-out of belt webbing.

摘要： A seat belt retractor has a rotating spool for retraction or pay-out of seat belt webbing. A locking ring is attached to one end of the spool. The locking ring is locked against rotation when a crash is sensed. A force limiting means allows further pay-out of the seat belt webbing after the locking ring has locked. Coupled in the force path between the spool and the locking ring, the force limiting means has a primary force limiting means; and a secondary force limiting means. The force limiting means include an elongate deformable member, arranged such that relative rotation between the spool and the locking ring causes a predetermined length of the deformable member to be deformed during a first stage of load limiting. The cross-sectional area of the deformable member is uniform over a major portion of the predetermined length and is reduced over at least one minor portion located a distance from the end of the member.

摘要： A spool for a vehicle safety restraint has a cylindrical central spool member made of two separate pieces. The cylindrical portion has a hollow section along its axis for accommodating seat belt webbing and a torsion bar, with a seat belt webbing entrance slot and a seat belt webbing exit slot. A filler plate is shaped to fit snugly into the entrance slot and to hold the parts of the spool assembly including the torsion bar and the spool against movement thereby holding the spool together.

摘要： A seat belt has a buckle tongue stop that is resiliently deformable. The buckle tongue stop may be deformable laterally or in its width and may be formed of compressible bumps. The seat belt allows a child seat to be secured in a vehicle according to European regulations yet still enables the buckle tongue to be supported on the belt webbing at a convenient location for an adult vehicle occupant.

摘要： A seat belt retractor has a rotatably mounted spool for supporting seat belt webbing. An emergency locking mechanism selectively locks the spool against rotation. An automatic locking mechanism selectively locks the spool against paying out webbing. A switch has a first position for activating the automotive locking mechanism in dependence upon a predetermined amount of webbing being wound off the spool, and a second position for deactivating the automatic locking mechanism in dependence upon a predetermined amount of webbing being wound back onto the spool. A gear connects the spool with the switch mechanism having a first and a second actuator tab on the gear. A pivotally mounted actuator member has an actuator pawl for locking the spool and parts engaging with the first and second tabs to move the switch between the first and second positions. The tabs and the engaging parts are radially oriented in line, one with the other.

摘要： A seat belt pretensioner has a rotary member that is connectable to a safety belt webbing retractor. A spool and a number of vanes are hingedly attached to the rotary member at spaced positions around the circumferential periphery of the rotary member. The rotary member is rotatably mounted in a housing having a wall facing, and spirally formed with respect to, the rotational axis of the rotary member to form a circularly tapering gas chamber between the rotary member and the wall of the housing. In the event of a crash a gas generator supplies gas which impinges upon vanes attached to the rotary member and causes the rotary member to rotate.

摘要： A vehicle seat belt system has seat belt webbing that is attached to a tongue adapted to be located in a buckle mechanism fixed to a load-bearing part of the vehicle. A generally vertically extending strap is adapted to be located in a position against a seat back. An adjustable webbing guide connects the generally vertically extending strap to the seat belt webbing; and there is a device for positively locking the webbing guide to the generally vertically extending strap at any one of a plurality of selectable locations on the generally vertically extending strap. A load limiter is operative for a child seat occupant but not operative for an adult seat occupant.

摘要： A seat belt retractor has a rotatable spool for retraction or payout of seat belt webbing wound thereon, depending upon the rotation direction of the spool. A locking wheel is attached to one end of the spool. The spool to is locked to the locking wheel when a crash is sensed. A force limiter allows further payout of the seat belt webbing after the spool has locked to the locking wheel, under the influence of a vehicle occupant's forward momentum. The force limiter includes a torsion bar attached at one end to the locking wheel and at the other end to the spool, and a secondary force limiter mechanism releasably coupled in the force path between the spool and the locking wheel, and a mechanism for de-coupling the secondary mechanism after a predetermined number of turns of the torsion bar. The locking mechanism has a locking element that is resiliently biased to a position wherein it locks the spool to the locking wheel and is held out of locking engagement by the secondary force limiting mechanism. The retractor is converted into a standard locking retractor after load limiting ensuring that the vehicle occupant is securely restrained against secondary impacts.
