  • Patent number: 11535191
    Abstract: Seatbelt assemblies for motor vehicle occupant restraint providing enhanced frontal impact restraint characteristics. Embodiments illustrated a displacement of the intersection positioned between the lap and shoulder belt portions of an active three-point type belt system. In one set of embodiments particularly useful with dual retractor systems, adaptive positioning provisions allow the point of intersection to initially occur at or near the seatbelt latch plate and when a restraint load occurs components release to allow repositioning of the intersection. In other embodiments best implemented in single retractor systems, a turning loop is provided which displaces the webbing slot separating the lap and shoulder belt sections from the buckle latch plate.

  • Patent number: 11254282
    Abstract: A tongue mechanism for use in an occupant restraint system also having a buckle mechanism and a webbing. The tongue mechanism includes a tongue member configured to selectively engage the buckle mechanism, a body formed over a portion of the tongue member, a slider, and a biasing member configured to laterally bias the slider. The body includes a body contact surface. The slider includes a slider contact surface and is configured to travel along a track between a first free position and a second locking position. When the slider is positioned in the first free position the tongue mechanism is free to slide along the length of the webbing, and when the slider is positioned in the second locking position a portion of the webbing is clamped between the slider contact surface and the body contact surface thereby preventing the tongue mechanism from sliding along the length of the webbing.

  • Patent number: 10605360
    Abstract: An electronic transmission range select actuator (ETRSA) includes a primary drive system that operates during normal operation. The ETRSA includes an output shaft that is connected to the system via a lock pin during normal operation. The ETRSA also includes a release mechanism having a secondary motor that operates during a power loss or failure of the system. The secondary motor drives a gear that rotates freely relative to the output shaft. Rotation of the gear results in axial movement of the gear toward the lock pin, which in turn causes disengagement of the lock pin from the output shaft, allowing the output shaft to rotate due to the biasing load of a torsion spring such that the output shaft is returned to the P-range position. Thus, the mechanism is configured to return the output shaft to the P-range during a power loss or failure of the first motor.

  • Patent number: 10369961
    Abstract: Systems and methods for installing retrofit seat belt systems with structural support for the lap and shoulder belts, while at the same time providing a low cost solution. In particular, some, or all of the loads, as required, are shared by an added support structure connected rigidly to a structural base, e.g., of a bus or other vehicle, via a base plate. As such the present teachings achieve compartmentalization around passengers in the event of a crash. Furthermore, unlike prior retrofit seat belt designs, the systems and methods of the present teachings uniquely facilitate a seamless transition for the different seat configurations and do not require complete replacement of the seats.

  • Publication number: 20110140503
    Abstract: The disclosed seat belt retractor may include a spool for retracting a seat belt, a torsion bar, a pre-tensioner, and a locking device. The torsion bar may disposed inside the spool, wherein one side of the torsion bar is connected to the spool, and configured to absorb energy of movement of an occupant while being deformed under torsion. The pre-tensioner may be positioned at one side of the spool and configured to generate a rotating drive force for rotating the spool in a retracting direction in a condition of rapid deceleration of a motor vehicle. The locking device may be capable of locking another side of the spool such that a rotation of the spool in a withdrawal direction is suppressed at both an operating time of the pre-tensioner and a non-operating time of the pre-tensioner.

    Abstract: To effectively operate a pretensioner using a plurality of balls and an energy absorption mechanism, to simplify the structure of an exhaust passage in the pretensioner, and to facilitate the working process of the exhaust passage. A pretensioner 15 includes a plurality of balls 20 serving as force transmission members and a piston 21 in a pipe 17. A piston body 21a of the piston 21 includes a shaft portion 21c and a substantially hemispherical head portion 21d. The piston body 21a is provided with an exhaust hole 21e extending in the axial direction and exhaust grooves 21f communicating with the exhaust hole 21e that define an exhaust passage. The exhaust grooves 21f prevent the exhaust hole 21e from being closed even if the head portion 21d of the piston 21 contacts the ball 20. Since the exhaust hole 21e and the exhaust grooves 21f are simply provided in the piston body 21a formed as a single member, the structure of the exhaust passage is simple, and working of the exhaust passage is easy.

The seatback includes a seatback frame and is selectively rotatable relative to the seat bottom from an upright position to a forward position. A seatbelt assembly includes a retractor coupled to the seatback frame and a belt selectively extendable from and retractable to the retractor. A first end of the belt is disposed in the retractor. A guide is coupled to the seatback frame and defines an orifice with the belt slideably extending through the orifice. The retractor and the guide are fixed relative to the seatback frame and the second end of the belt is fixed to the seatback frame. The retractor, the guide, and both ends of the belt rotate from the upright position to the forward position in response to a force exerted on the seatback frame during rapid deceleration of the seat assembly.

  • Patent number: 7837275
    Abstract: A multi-mode belt retractor including an interlocked attachment mechanism. The belt retractor and attachment mechanism are physically integrated in a single unit. In one embodiment, the retractor is shifted between modes by the operation by the attachment mechanism such that securing the attachment mechanism to an anchor point shifts the belt retractor into a locked mode. Releasing the attachment mechanism from the anchor point shifts the belt retractor into a free-wheel mode. In one embodiment, only a single user-operable button is provided, thus minimizing the opportunity for improper operation. One embodiment of the attachment mechanism is symmetrical, making it operable by a user's left or right hand.
