Lift-assist systems for adjustable objects are provided, which could include at least one of an enclosed spring and a substantially flat, elongated torsion spring. Suitable substantially flat springs could be configured to twist and untwist up to between 45-135 degrees when the seat or other object is adjusted between stowed and use configurations. In some preferred aspects, the spring could be made from a tempered steel material.

A flight attendant seat comprises a carrier having a guide with opposed first and second ends, and a storage compartment receiving the guide first end. The guide provides guidance along its length between its first and second ends. The seat comprises a plurality of segments, each slidingly mounted to the guide to allow a sliding movement of the segments along the guide and relative to the carrier device between a stored position of the segments within the storage compartment, and an exposed position of the segments. A seat element is pivotally mounted to a first of the segments pivotable between an inoperative and operative seat forming position. At least one backrest is mounted to at least a second of the segments. With the segments in their exposed position, the seat element, when pivoted to its operative position, together with the backrest(s), can be used as a flight attendant seat.

The various embodiments herein provide a modular shower seat connected to a wall structure comprising a mounting base component, a connecting elongated component and a primary functional component. The mounting base component is fixed against a wall structure through a holding medium. The mounting base component comprises a vertical base plate. The vertical base plate comprises a plurality of fastener holes and a plurality of vertical slots. The connecting elongated component is attached to the mounting base component through a plurality of fastening medium. The connecting elongated component comprises a pair of vertical bases. Each vertical base is orthogonally fixed to the vertical base plate by fitting the vertically opposite brackets into the vertically opposite slots of the vertical base plate. The primary functional component is fixed over the connecting elongated component.

An apparatus, method, and system of supporting a person such as a hunter or photographer in a seated position includes a cantilever arm extending from a supporting structure and a seat that is eccentrically mounted to the cantilevered arm. The cantilevered arm and eccentric seat can be attached to a supporting structure to allow the cantilever arm to pivot at its end opposite its seat over a range. Optionally the seat and cantilevered arm can be cinched along a tree or other vertical structures, placed on ground supported structure, or on other elevating structures.

A self-retractable step for assisting a user in elevating him or herself above a floor, is disclosed. The self-retractable step comprises a self-retractable foot member and a cylindrical assembly coupled with the self-retractable foot member. The foot member is configured to move from one position to another position. The cylindrical assembly comprises a rotary member, one or more spring members and a protuberance member. The rotary member is configured to move the foot member to a predetermined position. Further, the spring members coupled to the rotary member is configured to self-retract the foot member from the predetermined position. The protuberance member disposed at the cylindrical assembly is configured to act as a stopper to hold the foot member in a predetermined position on retraction by the spring members. The self-retractable step further comprises a load bearing member at a base of the foot member.

A completely integrated metallic seat pan with a negative stiffness includes a seat pan base, an internal metallic lattice, and a metallic seat pan cover surrounding the metallic lattice. The metallic lattice and seat pan cover elastically deform to absorb the weight of the crewmember and provide cushioning. The seat pan cover is contoured. Portions of the contoured seat pan cover may have greater or lesser cross-sectional thickness to provide variable negative stiffness at different locations on the seat pan.

An improved locker seat includes a pair of spaced-apart upstanding sidewalls having a pair of lateral edges. A generally horizontal seat is disposed between the lateral edges of the sidewalls. In a first mode, an air source is connected to an airway formed within the seat to create an airflow. The airflow from the air source creates a first temperature differential to cool the seat. In a second mode, an external or internal heat source provides heat to a top surface of the seat, creating a second temperature differential to heat the seat. The first and second temperature differential are distributed across the top surface of the seat. The seat is hinged to be movable about the hinge between an open and a closed position.
