A saddle for a crutch to assist a user in walking. The saddle comprises a frame having a support membrane disposed thereon, the frame and support membrane providing an inner lobe configured to rest against a torso of the user during use, an outer lobe configured to rest against an arm of the user during use, and a top portion connecting the inner lobe and the outer lobe and forming a U-shaped channel having an curved upper surface configured to fit within an armpit of the user with the U-shaped channel open along at least a portion of a downward facing side. A pivoting joint is attached. A spring mechanism having an upper portion is attached to the pivoting joint such that the joint is configured to allow the spring mechanism to move with respect to the frame along an arced path.

Biomechanically derived crutch

A rotatable shock absorber assembly for a crutch. A guide pin is removably fixable within the upper portion of a support leg. A piston comprises a flange arranged proximate a saddle, comprising a top surface having two or more arcuate rotation grooves defined therein, and a main body defining an elongate slot enabling the guide pin to be inserted therethrough, such that the piston can translate along the elongate axis relative to the guide pin. A joint, can operably couple the piston to the saddle. The joint can rotate about the elongate axis relative to the piston. A biasing mechanism is configured to urge the piston along the elongate axis toward the armpit of the user whereby the saddle can be held stable in the armpit of the user and the support leg can rotate about, and translate along the elongate axis during use.

Biomechanical and ergonomical adjustable crutch

Seating assemblies and methods are disclosed. A seating assembly can comprise a seat, a back support, and a frame component. The frame component can extend from a bottom portion, positioned near an underside of the seat, to a top portion, configured to maintain the back support at a position above the seat. The back support can laterally extend from a left edge portion to a right edge portion and can include a spring member at or near each of the left and right edge portions. The spring member can include at least one undulation or are providing integrated compression adaptation to a user. The seating assembly can further comprise a tilt mechanism, engaged with the frame component, including one or more leaf springs and a spring contact assembly. The spring contact assembly can be positioned on a top side of the one or more leaf springs.

Ergonomic seating assemblies and methods

A crutch having a first side direction, a second side direction opposite the first side direction, a third side direction perpendicular to the first side direction and a fourth side direction opposite the third side direction, the crutch including an elongate leg having a top end, a top portion, a middle portion, a bottom portion, and a bottom end, wherein the elongate leg extends from a saddle to a foot and has a handle disposed on the middle portion, wherein the saddle extends in an elongate shape between the first side direction and the second side direction, wherein the handle extends in an elongate shape between the first side direction and the second side direction, wherein the elongate leg middle portion is to the third side direction of an axis extending between the leg and the foot, wherein the elongate leg middle portion is to the first side direction of an axis extending between the top end of the elongate leg and the bottom end of the elongate leg; and wherein the handle is cantilevered and has a fixed end and a free end.

Crutch saddle

Seating assemblies and methods are disclosed. A seating assembly () can comprise a seat, a back support (), and a frame component (). The frame component can extend from a bottom portion (), positioned near an underside of the seat, to a top portion (), configured to maintain the back support at a position above the seat. The back support can laterally extend from a left edge portion () to a right edge portion () and can include a spring member () at or near each of the left and right edge portions. The spring member can include at least one undulation or arc () providing integrated rated compression adaptation to a user. The seating assembly can further comprise a tilt mechanism (), engaged with the frame component, including one or more leaf springs () and a spring contact assembly. The spring contact assembly () can be positioned on a top side of the one or more leaf springs.

Crutch

An elastomeric load bearing surface with different load support characteristics in different directions. In one embodiment, the surface includes an elastomeric membrane that is oriented in only a single direction, for example, by compression or stretching. In another embodiment, the surface includes mechanical structures, such as connectors, variations in thickness and apertures, that vary the load support characteristics in different directions. In another aspect, the present invention provides a multilayer load bearing surface in which the layers cooperate to provide a controlled force/deflection profile that is variable in different regions of the surface. In one embodiment, the upper layer includes a plurality of loosely connected nodes and a lower layer having a plurality of resilient elements that separately support each node.

Load bearing surface

A seating structure includes a central spine and an upper back structure having a pair of arms extending upwardly and outwardly from the central spine. The upper back structure is pivotally connected to the central spine about a first horizontal axis. A back support structure is pivotally connected to the spine about a second horizontal axis and is pivotally connected to the ends of each of the arms about a third horizontal axis.
