    Abstract: A linear latch interconnecting a pivotally adjustable seatback with a frame location of a vehicle interior. A bracket supported housing pivotally secures to a surface of the frame. An elongated member is supported in linearly displaceable fashion to the bracket and exhibits a plurality of spaced apart apertures. A forward extending end of the member connects to the seatback. A coil spring influences seats over the elongated member and biases the same in a first lineal direction away from the housing. A pair of pins are anchored to an inner support member within the housing and which is biased in a first lateral direction to cause the pins to seat through aligning apertures in the elongated member. A cable retracting mechanism displaces the inner support member in a second opposite direction, causing the pins to outwardly displace from the elongated member and to permit adjustment relative to the housing in order to define a range of seatback motion between upright design and rear recline positions.

  • Patent number: 7380884
    Abstract: The present invention provides a switching apparatus having a design intended to reduce wear on its key part. In an embodiment of the invention, a rotatable member is rotatably fixed on a pivot. A slidable bearing member has a first surface for engaging the rotatable member in a non-sliding manner, and an opposite second surface for slidingly engaging an abutment. Any significant wear on the switching apparatus is more likely to occur between the sliding member and the abutment, rather than between the rotatable member and the sliding member. In an embodiment, one of the rotatable member and the slidable bearing member includes a protuberance, and the other of the rotatable member and the slidable bearing member includes a corresponding indentation for engagement with the protuberance. The join formed between the protuberance and indentation provides a substantially non-sliding engagement between the rotatable member and the slidable bearing member.

  • Patent number: 6910738
    Abstract: An adjustable pivot rotatably supports and adjusts a position of a pivoting member within a housing. The adjustable pivot includes a central cylinder defining a first axis and rotatably supporting the pivoting member. A second cylinder extends from the central cylinder and defines a second axis offset from and parallel to the first axis. The second cylinder is supported by the housing and operable for rotation about the second axis to an adjustment position. Rotation of the second cylinder to the adjustment position causes the first axis to orbit about the second axis to an adjusted position. In this manner, the pivoting member is adjustably positioned within the housing.

  • Patent number: 6789848
    Abstract: An articulation mechanism has a central part and a head part each made of a pair of shaped elements. The pairs of shaped elements form inner and outer shells. The inner shells are positioned inside the outer shells. The pairs of shaped elements are pivotable relative to one another and lockable relative to one another in several positions in one pivot direction. The outer shells have inwardly oriented projections and the inner shells have openings. A slide is moveably arranged inside the inner shells. The slide has locking members projecting through the openings of the inner shells and engaging intermediate spaces of the projections. A spring acts on the slide in an engagement direction of the locking members relative to the projections. The projections are shaped such that the locking members automatically reach a locking position in a first pivot direction of the head part.

  • Patent number: 6779838
    Abstract: A foldable chair includes a leg assembly and a reclining back connected together by a pair of joint assemblies. Each joint assembly includes a through hole for receiving a support member of the reclining back, and a through channel for accommodating a control device that adjusts the reclining angle. The control device comprises a spring member and an adjustment block to be engaged and disengaged with a saw-tooth member formed on the lower end of the support member. A control button is connected to a handle of the adjustment block. The reclining angle can be adjusted when the control button is pulled to disengage the adjustment block with the saw-tooth member. The control button may also be coupled with the handle using a coupling device. By having the coupling device, the control button can be pushed to disengage the adjustment block with the saw-tooth member.

  • Patent number: 6742843
    Abstract: The present invention discloses an overload protection mechanism for a cable actuated feature on an office chair. The overload protection device allows a person seated in the chair to move a handle to actuate the particular feature of the chair, for example, a reclining backrest, even when the seated person's weight on the backrest prevents the backrest locking mechanism from engaging or disengaging. The movement of the handle causes the cable to move even when the locking mechanism connected to the opposite end of the cable is unable to engage or disengage. The mechanism stores the motion of the cable in a spring device connected to the movement actuators by a rack and pinion gear system. When the binding is released from the actuators, the mechanism moves as originally intended, motivated by the force of the decompressing springs.

    Abstract: Drive wheel axle assemblies (34, 34A) and caster wheel assemblies (94, 252) are mounted to a wheelchair frame (4, 222). One axle assembly (34) includes an axle adjustment tube (40) secured to the frame and an axle housing (56), defining an axle bore (58), toollessly mounted to the axle adjustment tube at any of several rotary orientations to determine the camber of the drive wheel (36) mounted to the axle assembly. The front to rear position of the axle housing can also be adjusted in a toolless manner using a quick release pin (66). The height of the front end (10) of the frame is changed, to ensure that the caster wheel pivot axis (96) remains vertical, without tools by mounting a caster wheel (98) at various vertical positions within a caster spool housing (100) without exposing the user to oil and grease on the spindle (120) and bearings (121). Another axle assembly (34A) permits the height of the drive wheels (254) to be changed without the used tools.

  • Patent number: 5806933
    Abstract: A head rest and restraint assembly has, as its principal component, a padded, shaped arm which has one end thereof contained in a mounting member. The contained end has a splined portion thereon which is adapted to mate with an interior splined portion of the mounting member, which comprises a hollow cylinder. Adjustment of the angular arm is accomplished by pushing the end of the arm into the cylinder against the force of a coil sprint until the splines dis-engage, allowing rotation of the arm, when the arm is released, the spring forces the splines into re-engagement, thereby fixing the angular orientation of the arm. Pairs of arms mounted in brackets, for example, can be used with existing vehicular headrests, or a replacement or new head rest may be formed with bores to accept and hold the mounting means.
