Abstract: A car seat has a base for placement on a vehicle seat and a seat shell attachable to and detachable from the base. A latch mechanism is biased to a latched arrangement attaching the shell to the base. A release actuator is connected to the latch mechanism and can move the latch mechanism to a released arrangement, detaching the shell from the base permitting its removal from the base. The shell can be optionally adjustable on the base between at least two different recline positions. The latch mechanism in the latched arrangement can then also retain the shell in one of the recline positions. A recline actuator can be connected to the latch mechanism and can move the latch mechanism allowing adjustment of the shell recline position but not permitting removal from the base.

Abstract: An improved wheel assembly comprises a caster fork, a caster wheel rotatably supported by the caster fork, and a caster swivel post defining an axis about which the caster fork rotates. The caster swivel post is being adapted to rotate about a pivot axis within a cylindrical housing. Alternatively, the wheel assembly has an adjustable axle for varying the camber angle of a wheel. The wheel assembly comprises a housing and an axle supported by the housing. The axle in turn rotatably supports a wheel. The axle is adapted to rotate about a pivot axis within a cylindrical housing.

Abstract: A wheel mount assembly adapted for use in securing a camber tube to a wheelchair frame comprises an axle plate, at least one axially displaceable member adapted to be fixed in relation to the axle plate, and at least one radially displaceable member adjacent the axially displaceable members. The axially displaceable member is adapted to be axially displaced to cause the radially displaceable member to be displaced to tighten against the camber tube to hold the camber tube in place.
