Abstract: A bicycle seat height adjustment method is provided for changing a height of a bicycle seat. The method includes operating an operating device to output a seat raising command which is received by a motorized seat height adjustment mechanism to adjust the seat height. The method further includes releasing the operating device after the operating of the operating device. The method further includes raising the bicycle seat using the electric motor to a higher seat position that is higher than a previous seat position existing immediately prior to the seat raising command, the raising of the bicycle seat occurring only after the releasing of the operating device such that the bicycle seat remains stationary until the operating device is released.

Abstract: A multi-position seat for a kayak or other watercraft includes a seat frame and a pivotally connected back support. A pair of side elevation adjusters engages the seat frame on its lateral sides. Each adjuster includes a thumbwheel adjuster within an elevator traveler within a side frame, the traveler engaging a threaded shaft that is held in a fixed rotational position. The frame includes a tunnel structure associated with a front cross member. A strap passes through the tunnel, exits at lateral sides of the front cross member, and connects to lateral sides of the pivotally connected back support. The strap is user-adjustable in length so that the angle of the back to the seat is adjustable. The seat is thereby adjustable in angle front-to-back, can be canted left-to-right, changed in elevation, and the back support can be adjusted in angle and elevation.

Abstract: A patient transport apparatus. The patient transport apparatus of the present invention is articulated and sized to fit between the body and the open door of virtually all vehicles. Further, the patient transport apparatus uses a height-adjustable seat that is aligned with the vehicle seat to allow for simplified extraction of the patient from the vehicle. The height-adjustable seat lowers to just above ground height making the recovery of a fallen patient easier. A set of casters allows omni-directional travel of the patient transport apparatus for precise placement and a pair of primary motion wheels makes linear travel easier while providing a turning radius substantially approaching zero.

Abstract: A motor and reversible drive move a child safety seat between a sitting and reclining position on a base secured by a vehicle safety belt. A drive shaft and gear system, double action winch and cord system, hydraulic drive, screw drive, or other drive system positioned within an enclosed base move the safety seat reversibly. A remote control operable by the driver of the vehicle controls the seat motor. An interconnecting system between the safety seat and the base maintains the safety seat in proximity with the vehicle seat back. The electric motor may be battery powered or plugged into the cigarette lighter of the vehicle.

Abstract: A linkage assembly is used to vertically adjust the position of a seat. The linkage assembly includes a first link that is connected to a second link without the use of fasteners. The first link has a first mounting portion and the second link has a second mounting portion. The first mounting portion is deformed into engagement with the second mounting portion to rotatably connect the first link to the second link. In one embodiment, the first mounting portion is an extrusion that extends through an aperture in the second link. An end of the extrusion is deformed into engagement with the second link to form a lip to lock the first link to the second link and allow relative rotational movement between the first and second links while eliminating relative linear movement therebetween. In an alternative embodiment, portions of the first and second links are deformed into locking engagement.
