A back-support board including a leg assembly, a support assembly and an assistance assembly is disclosed. The leg assembly includes adjustable legs which have insertable pegs within for reinforcing the strength of the legs to be able to support weight thereon in a stable and safe manner. The support assembly includes a base having a reinforcing layer atop and further having a top layer thereon. The top layer being of a carpet or rubber material. Once a user needs to work underneath a tight space such as under a sink, the back-support board is adjusted to a proper height and allows for the user to lay down on the back-support board to comfortably work on the necessary task with their body supported on the back-support board. The back-support board is adjustable to allow fitting under different tight spaces for completing different tasks in a more comfortable manner.

A rolling work platform assembly that allows rolling while in a kneeling position includes a first plate. A pair of knee pads and a seating unit are selectively engageable to the first plate. The knee pads cushion the knees of a user kneeling upon, or separated from, the first plate. The seating unit engages and pads buttocks of the user kneeling upon the first plate. A set of first wheels engaged to a lower face of the first plate facilitates locomotion of the first plate and the user positioned thereupon.

Seat assemblies are provided. In some embodiments, a seat assembly includes a seat member having a first seat surface, a second seat surface, and a third seat surface opposite the second seat surface. The third seat surface is substantially parallel to the second seat surface and the first seat surface is substantially perpendicular to both the second seat surface and the third seat surface. The seat assembly also includes a first side panel affixed to the second seat surface and a second side panel affixed to the third seat surface. Each one of those panels is substantially perpendicular to the first seat surface. The seat assembly further includes a bin movably affixed to the first side panel and the second side panel. The bin includes an open compartment and can be moved between a closed position that obstructs the compartment and an open position that permits access to the compartment.

A collapsible seat having a base and configured to alternatively take a use position and a storage position wherein the seat is collapsed. The seat includes first and second modules. The first module rotates in a vertical plane having longitudinal elements forming a deformable quadrilateral. The first module is articulated about an axis of rotation mounted on a fixed support and, in the use position, at least two longitudinal elements are in surface contact blocking rotation of the first module along a direction of rotation. The second module, mobile in rotation in the same vertical plane as the first module, has a support leg for surface contact with the ground in the use position and a connecting rod fixed between the first module and the support leg. In the use position, the connecting rod and the support leg are in surface contact blocking rotation of the second module.

A technician's work chair having a frame, an air cushion assembly, a seat assembly, and air hose and a pivoting hose support. The air cushion assembly is attached to the frame and supports the frame on an air cushion formed above a floor surface. The seat assembly has a cushion portion on the frame and a seatback portion with a mechanism that changes an angle of inclination of the seatback portion. A technician seated in the seat assembly can ergonomically operate tools and complete tasks with arms raised over the technician's head. The air hose having a first end connected to a compressed air source and a second end connected to the air cushion assembly. The pivoting hose support biases the air hose to move in a rearward direction relative to the technician's work chair.

The height-adjusting stool is a seat, which may change height between a minimum height and a maximum height by activating a motor to move a scissor jack located beneath the seat. The motor may be battery-operated. A plurality of wheels may allow the height-adjusting stool to be repositioned by rolling to one side or the other. One or more wheel locks may prevent the plurality of wheels from rolling when stationary positioning is desired. A three-position switch may allow the user to move the seat up or down or to cease motion of the seat.

Wearable systems to partially support the weight of a human user engaged in task performance in a crouched position at or near ground level are presented herein. In one aspect, the wearable systems employ passive mechanisms and the configuration of the support mechanisms is changed by movements of the body of the human user while transitioning from a standing position to a crouched position, and vice-versa. In a further aspect, each passive lower body support assembly includes an auxiliary body support structure to enhance the support of the human user in a crouched position. In another further aspect, each auxiliary body support structure is deployed in coordination with the movement of the seat support structure that supports the human user. In some embodiments, one or more body support structures are constructed from an elastic material that conforms to the ground surface when loaded by the weight of the human user.

A creeper for accessing cabinets includes a first end and a second end. The creeper includes a base support structure having a top surface, a bottom surface, and a plurality of side walls extending between the top surface and the bottom surface. The base support structure also includes a cabinet entry first end that is shaped and dimensioned for positioning within a cabinet and an exposed second end that is shaped and dimensioned to sit outside of the cabinet when cabinet entry first end of the creeper is positioned within the cabinet for use. A downwardly extending leg assembly is secured along the bottom surface of the base support structure. The cabinet creeper may be used for accessing a cabinet or as a seat with the user sitting directly upon the downwardly extending leg assembly.

The present invention relates to a single-legged portable working chair using a compression repulsive force of a spring body, wherein: when used, the telescopic single-legged portable working chair is worn on a user's body such that, when the user sits down, the spring body is compressed by the weight of the user's body to store power, and when the user stands up, the spring body pushes up the user's body using the compressed power, so that the power consumption required for the sitting and standing actions of the body can be reduced; when the user repeatedly lifts a weight, the load applied to the user's joints and muscles is alleviated by the magnitude of a repulsive force of the spring body.

The present invention is a moveable stool that includes a wheeled member having wheels, a stably support member and at least one flexible element. Stably support member is formed of a bottom cavity, a top flat surface for user to stand on and support element(s). When a user is not standing on top flat surface, then the wheels are free to move and stool is displaceable from one position to another. After the stool reaches at desired position and the user steps up on top flat surface, non-skid support element(s) connects with ground wheels of wheeled member are restricted from movement. Restricted movement of wheels prevents movement of stool on ground/floor. When user steps down from top flat surface, flexible element(s) retracts stably support member which raises support element(s) and disconnects contact between support element and ground. Wheels in contact with ground/floor are freed rendering stool again for portability.
