The invention discloses a belt retractor comprising a frame (10), a belt reel (12) which is arranged rotatably in the frame (10) and can receive a seat belt (14), at least one load limiter (16) which enables the belt reel (12), when it overcomes a braking torque provided by the load limiter (16), to rotate relative to the frame (10) so as to release seat belt (14), and a switchable clutch (26) including a switching cage (22) and coupling elements (24), wherein the switching cage (22) can be shifted by means of an actor (28) from an open position in which the coupling elements (24) are maintained disengaged from the belt reel (12) to a closed position in which the coupling elements (24) engage the belt reel (12). In order to achieve a compact design, the belt retractor includes an actuator (38) which is coupled to the actor (28) and a freewheel (40) which couples the switching cage (22) to the actuator (38) so that the actuator (38) can shift the switching cage (22) from the open position to the closed position.

The invention relates, inter alia, to a belt retractor (10) for a safety belt device, with a belt reel (20) for winding up and unwinding the safety belt, a pretensioner drive (40) and a pyrotechnic tensioner drive (30), wherein the pretensioner drive (40) has a force-flux-control element (100) which, in a deactivation position, interrupts the force flux between pretensioner drive (40) and belt reel (20). It is provided that the pyrotechnic tensioner drive (30) has one or more drive elements (33) which, after activation of the pyrotechnic tensioner drive (30), is or are set into motion, and, after activation of the pyrotechnic tensioner drive (30), the force-flux-control element (100) is adjusted directly or indirectly by the drive element (33) orin the case of a plurality of drive elements (33)by at least one of the drive elements (33) of the pyrotechnic tensioner drive (30) into the deactivation position.

In a coupling (18) for a belt tensioner (10) in a vehicle comprising an input element (26), an output element (34), a coupling element (28) which is movably supported between an initial position and an activated position and in the activated position couples the input element (26) to the output element (34), and a control element (36) which upon movement of the input element (26) relative to the control element (36) moves the coupling element (28) between the initial position and the activated position, the control element (36) is coupled to an inertia mass (36).

A pet restraint system for a vehicle is provided. The pet restraint system includes a leash configured to connect to a restraint device on a pet, a wearable device comprising one of a collar and a harness configured to be worn on the pet and connected to the leash, a retractor device coupled to the leash and configured to be secured to a support structure on the vehicle, a sensor for detecting an expected condition of the vehicle, and a controller for controlling the retractor to retract or lock the leash based on the determined expected condition of the vehicle.

The invention relates, inter alia, to a belt retractor (10) for a safety belt device, with a belt reel (20) for winding up and unwinding the safety belt, a pretensioner drive (40) and a pyrotechnic tensioner drive (30), wherein the pretensioner drive (40) has a force-flux-control element (100) which, in a deactivation position, interrupts the force flux between pretensioner drive (40) and belt reel (20). It is provided that the pyrotechnic tensioner drive (30) has one or more drive elements (33) which, after activation of the pyrotechnic tensioner drive (30), is or are set into motion, and, after activation of the pyrotechnic tensioner drive (30), the force-flux-control element (100) is adjusted directly or indirectly by the drive element (33) orin the case of a plurality of drive elements (33)by at least one of the drive elements (33) of the pyrotechnic tensioner drive (30) into the deactivation position.

In a belt retractor (10) for a seat belt comprising a belt reel (12) onto which webbing (14) can be wound while being spring-loaded and comprising a tensioning device (16) which is adapted to act on the belt reel (12) in a winding direction (A), a control (18) is provided which is adapted to activate the tensioning device (16) when the seat belt is unloaded and not fastened.

A belt tensioner for a seatbelt system comprising a spur gearing (18). The spur gearing (18) comprises at least one motor gearwheel (24) and at least a first stepped wheel (26) and a second stepped wheel (28). The motor gearwheel (24) forms a first gear stage (34) with the first stepped wheel (26), and the first stepped wheel (26) forms a second gear stage (36) with the second stepped wheel (28). The motor gearwheel (24) and each of the stepped wheels (24, 26) include helical teeth, and the helix angle of the helical teeth of the second gear stage (36) is determined depending on the helix angle of the first gear stage (34). The overlap ratio of at least one helical toothing is not integer.

In a coupling (18) for a belt tensioner (10) in a vehicle comprising an input element (26), an output element (34), a coupling element (28) which is movably supported between an initial position and an activated position and in the activated position couples the input element (26) to the output element (34), and a control element (36) which upon movement of the input element (26) relative to the control element (36) moves the coupling element (28) between the initial position and the activated position, the control element (36) is coupled to an inertia mass (36).

A controllable clutch (18) for a belt tensioner (16) comprises a drive member (32), a driven element (24) and a clutch pawl (40) that is movably supported on the input side (30) between a home position and an engaged position and in the engaged position couples the drive member (32) to the driven element (24), wherein the clutch pawl (40) is tension-loaded in the engaged position.
