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 dosed position that obstructs the compartment and an open position that permits access to the compartment.

An embodiment is a lightweight, packable seat that includes a seat platform, two shafts for support, straps with respective buckles, or similar, that secure the seat to a vertical object, such as a tree. The seat may be made of a lightweight flexible material that is held in a stiff orientation that extends outward from the tree through coupling to the upper strap at the proximal end of the seat and the shafts at a distal end of the seat, where the shafts project downward toward a proximal location at the tree at the lower strap. Use of the lower strap means that the shafts do not contact a ground surface, thereby providing stability. The shafts may be made of composites or aluminum, for example, such that the entire weight of the seat may weigh just a few ounces while exhibiting strengths and stability.

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.

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.

An adjustable luggage trunk stroller with seat cushion is provided. The luggage trunk stroller has an innovative structure, comprising a casing, a rod assembly, a seat cushion and a seat belt. As comparing to the conventional structure, the casing can be manually rotated for changing the tilt angle of the casing at 090 degrees and fastened to a certain position with the coordination of the rod assembly. When disposing the casing at a certain angle, the seat cushion can be swayed and extended for an infant to sit. Or, when the casing is disposed in a horizontal planar state, the seat cushion can be swayed and folded for the infant to lie flat. Thus, the luggage trunk stroller is capable of carrying the infant during walking. The luggage and the infant can be carried at the same time for effectively improving the added value of the luggage trunk stroller.
