A medical chair includes a base, a seat section, and a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position. The chair further includes a scissor mechanism coupled to the leg rest to extend and contract the leg rest and an actuator mounted on one end relative to the seat section and having an extendible driving end coupled to the leg rest wherein when the extendible driving end extends the extendible driving end pivots the leg rest about the pivot axis and extends the scissor mechanism.

A wheelchair comprising a seat back, a seat bottom, a frame, two front wheel assemblies, two drive wheels, two wheelchair wheels, and an anti-rollback wheelchair braking system consisting of two braking units, each unit comprising a housing cylinder body cap, a housing cylinder body, a housing cylinder mounting assembly, a wheelchair mounting assembly, rotatable toggle clamp direction selection lever, an anti-rollback, one-way, brake assembly, and a toggle clamp assembly for engaging the said anti-rollback, one-way, brake assembly with a wheelchair wheel. A parking brake assembly may also be included. The invention may be manufactured and sold as a whole wheelchair assembly or a retrofit kit for standard wheelchairs.

The present invention provides an assembly having a wheelchair and a lift assembly to urge the seat surface upward with respect to the frame from a lowered position when supporting the seated individual during use to an elevated position with respect to the frame assisting the individual during ingress or egress to or from the wheelchair. The lift assembly may include a mechanical linkage and an actuator. The assembly also provides at least one brake configured to block rotation of the wheelchair wheel with respect to the wheelchair frame in a locked state and disengaging with the wheels to allow rotation of the wheel with respect to the frame in an unlocked state. The assembly also provides a brake linkage communicating between the lift assembly and the brake to move the brake into the lock state when the seat surface moved to the elevated position.

Disclosed herein is a system/apparatus for storing, use in therapy, and transporting a (bionic) exoskeleton. The apparatus includes a frame comprising a plurality of legs, a seat, and a back which are operable for being moved between one or more configurations. The seat of the frame defines a seat surface configured for engagement with an exoskeleton. Furthermore, the back of the frame is operably engaged with the seat such that the back of the frame may be folded over, into, or extended from the frame to reduce an overall profile size of the apparatus in a collapsed or folded configuration. The apparatus may further include a pair of footrests defined along the legs that rotate in a lateral direction relative to the frame for the patients ease of transition into the exoskeleton. The frame also includes a locking mechanism that aids to from a storage configuration or a ready configuration.

The present application relates to a cable tension adjuster for a manually operated, height-adjustable wheeled vehicle. The vehicle includes a brake assembly including a brake cable assembly and a brake cable housing shaped to enclose an excess portion of the brake cable assembly. The brake assembly includes a cable adjuster coupled to the brake cable assembly, where the cable adjuster is enclosed by the brake cable housing. The brake cable housing provides an access port to access the cable tension adjuster.

Described herein are various improvements to mobility devices. These improvements include, for example, adjustable lateral body supports, multi axial supports for accommodating movement of the pelvis during walking, frame folding assemblies for accommodating storage and transportation, detachable support couplings for supportive accessories, foldaway footplate assemblies for allowing users to rest, wheel brake systems, caster wheel systems, suspension support systems, control button assemblies, and center of gravity adjustment assemblies. One or more these improvements can be combined into various mobility devices as will be described in more detail hereinafter.

An electric lifting and moving machine, including a bearing assembly consisting of a seat board to bear a user; a supporting assembly having a chassis; an electric lifting assembly having a motor driving assembly and a lifting assembly in transmission connection with each other; the lifting assembly is arranged on the chassis; at least one connection rod connected to the lifting assembly and the bearing assembly so that the lifting assembly drives the bearing the bearing assembly to move upward or downward; at least one castor on a bottom part of the chassis; and at least one foot brake assembly arranged on the chassis corresponding to the castor; in a parked state, the foot brake assembly contacts the castor to prevent it from rotating.

A patient support apparatus that is adaptable to multiple modes of transport includes a variable length base and a drive system that includes two independently drivable wheels that are responsive to inputs from a user to steer the patient support apparatus.

A person support apparatus includes a base frame with a plurality of caster wheel assemblies, each of the caster wheel assemblies including a caster brake actuator movable between a total braking position and a non-braking position. A linkage system is coupled to the caster brake actuators for controlling the caster brake actuators and is operable to move the caster brake actuators between their total braking positions and their non-braking positions. The linkage system is configured to compensate for tolerances in the linkage system wherein the linkage system can control the caster brake actuators to simultaneously move between their total braking positions and their non-braking positions.

A locking system of a wheelchair is disclosed. The locking system includes a locking member, an actuator, a locking frame, and an opening. The opening is disposed within the locking frame. The actuator is in communication with the locking member and is configured to move the locking member within the opening. The actuator is operable in a retracted operation state and an extended operation state. The actuator is configured to move the locking member in an upward direction when the locking system is set from the extended operation state to the retracted operation state. The actuator is configured to move the locking member in a downward direction when the locking system is set from the retracted operation state to the extended operation state, and the locking member is naturally biased in the extended operation state.
