Belt Winds Upon Take-up Reel Patents (Class 297/475)
  • 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.

  • Patent number: 7896434
    Abstract: A seat assembly for a vehicle includes a seat bottom and a seatback. 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.

  • Publication number: 20100207444
    Abstract: A vehicular seatbelt device whereby slack in a lap belt is sufficiently eliminated according to a traveling state of a vehicle, and a comfortable ride for a vehicle occupant is maintained. A seatbelt device comprises a belt retraction part and an actuator for driving the belt retraction part. The belt retraction part pulls part of a belt in a direction opposite the direction in which the belt is wound up by a belt reel so as to restrain the vehicle occupant. A controller includes a plurality of pre-set control modes for controlling a motor and the actuator in accordance with the traveling state of the vehicle, and selects and implements one control mode corresponding to the traveling state from among the plurality of control modes. The control modes include a mode for drivably controlling both the motor and the actuator, a mode for drivably controlling only the motor, and a mode for drivably controlling only the actuator.

  • Publication number: 20100127553
    Abstract: A vehicle seat has a seat base and a seatback. The vehicle seat has as a permanent feature a pair of seat belt guides positioned such that when a lap portion of a seat belt webbing is received in both of the seat belt guides the lap portion of the seat belt webbing intersects the seat belt guides at a selected distance from a forward face of the seatback. Each of the seat belt guides restricts movement of the lap portion of the seat belt webbing away from the forward face of the seatback. The seat belt guides direct the lap portion of the seat belt webbing across the seat base along a path such that the lap portion of the seat belt webbing interacts with the lower body of a child when the vehicle seat is occupied by a child aged three to twelve years and under 150 cm in height.

  • Publication number: 20100127554
    Abstract: A seatbelt retractor according to the present invention is configured in such a manner that a cylindrical rotor (24) of an electric motor in a spool is formed into two members in the axial direction, that is, a two-piece member including a first rotating member (24a1) and a first rotating shaft member (24b1), and a second rotating member (24a2) and a second rotating shaft member (24b2), and these two members are coupled. A torsional portion (42a) of a torsion bar (42) is penetrated through an inner hole (24b11) of a rotating shaft member (24b) including first and second rotating shaft members (24b1), (24b2) in the axial direction. Accordingly, even though the maximum outer diameters of first and second head portions (42b), (42c) of the torsion bar (42) are set to be larger than the inner diameter of the inner hole (24b11), the torsion bar (42) can be integrated into the rotor (24) easily.
