Abstract: A pivot device having asymmetric friction torque is provided. The pivot device includes a shaft extending along a longitudinal axis, a sleeve surrounding the shaft, the sleeve defining a gap extending longitudinally, the sleeve and the shaft being configured for rotation with respect to one another about the longitudinal axis, and a helical compression element surrounding the sleeve and exerting a compressive force onto the sleeve, wherein a first torque required to rotate the sleeve and the shaft with respect to one another in a first direction differs from a second torque required to rotate the sleeve and the shaft with respect to one another in a second direction opposite to the first direction. A method for providing a pivot device asymmetric friction torque is also provided.

Abstract: According to one aspect, a releasable roller clutch includes a shaft and a clutch housing positioned around the shaft. The shaft and clutch housing together defining a space there between with rollers positioned in said space. The rollers permit rotation of the shaft relative to the clutch housing when in an unlocked position in which the rollers are not wedged and prevent rotation of the shaft relative to the clutch housing when in a locked position in which the rollers are wedged. A cage extends into the space defined between the shaft and clutch housing. The cage is moveable relative to the clutch housing between an unlocking position and a locking position. The cage has a contact edge positionable to prevent the rollers from moving from the unlocked position to the locked position when the cage is in an unlocking position. The releasable roller clutch permits rotation of the shaft relative to the clutch housing in both directions when the cage is in the unlocking position.

Abstract: An adjustable headrest 300 includes a guide 360 configured to be coupled to a seat, a head support 302 coupled to the guide and configured to be movable along an adjustment path relative to the seat, and a slider 370 having a surface defining a recess 373 receiving the guide such that the surface of the slider contacts a surface of the guide. The adjustment headrest further includes a retainer 390 positioned to urge the surface of the slider against the surface of the guide, thereby maintaining friction between the surface of the slider and the surface of the guide and resisting unintended movement of the slider with respect to the guide along the adjustment path. Also, a friction module and a friction hinge are provided, which can be incorporated into an adjustable headrest or other assemblies in which sliding and/or hinged components are desired.
