A foldable chair has frames connected to one another by cross supports, bases connected to the frames by base supports and frame supports, with springs secured between the base supports and frame supports to allow for back and forth movement of the frames when a user is seated in the chair. The foldable chair includes a pliant membrane providing a seating surface for supporting the user.

A linear actuator is configured to be connected between a platform and a structure or ground for displacement of the platform relative to the structure or the ground. The actuator comprises a base, and an output displaceable linearly relative to the base. A first plurality of idlers are on the base, and a second plurality of idlers are on the output. An actuator unit has a reciprocating rotational output. A tensioning member has a first end connected to the rotational output of the actuator unit, and a second end connected to an anchor point on one of the output and the base, the tensioning member being routed from the rotational output, through the first plurality of idlers and the second plurality of idlers and to the anchor point for converting a winding/unwinding of the tensioning member into a translation of the output.

A chair chassis includes: a base, provided with an accommodation chamber; a backrest support; a memory stopper, disposed on the backrest support, wherein the memory stopper is provided with a first arc surface facing the base; a locking slider, slidably disposed in the accommodation chamber of the base, wherein the locking slider is provided with a second arc surface disposed opposite to the first arc surface, and a side of the locking slider is provided with a first rack; a first elastic member; and an elastic slider, slidably disposed in the accommodation chamber of the base, wherein one end of the elastic slider is provided with a second rack, wherein the second rack is meshable with the first rack. Accordingly, the chair chassis according to the embodiments of the present disclosure achieves reclination memory adjustment of a backrest of the chair.

An electrically controlled chassis includes: a chassis body; an electrical control box, internally provided with an accommodation space; a drive motor, configured to control lift adjustment of the chassis of the chair and pitch adjustment of a backrest of the chair; a winding mechanism, connected to an output shaft of the drive motor; a first pull cord, reversely wound on the winding mechanism; a second pull cord, normally wound on the winding mechanism; a backrest adjustment mechanism, disposed on the chassis body, and fixedly connected to the other end of the first pull cord; and a chassis lift mechanism, disposed on the chassis body, and fixedly connected to the other end of the second pull cord.

A gaming chair with audio output. The gaming chair includes a movable stand member, a seat member, a backrest member, a plurality of speakers, a Bluetooth transmitter, a power supply, and an inverted triangle wiring. The seat member is disposed over the movable stand member. Further, the backrest member is hingeably coupled to the seat member. Furthermore, the inverted triangle wiring is adapted to electrically couple the plurality of speakers, the Bluetooth transmitter and the power supply to enable an electrical connection therebetween.

A hunting chair is provided. The hunting chair includes a seat, a seat support structure coupled to the seat at an angle, and a back support. The seat support structure consists of two legs and at least one cross rail connecting the two legs. The back support is positioned between the two legs above the seat.

The convertible hand truck and chair device may combine the advantages of a wheeled hand truck with the advantages of a folding chair. Such a design may allow a user to transport large or heavy items from one location to another using the hand truck, and to then utilize the hand truck as a chair device for sitting. By way of example, a user going to the beach or a camp site may carry most or all of their needed items, such as coolers, foodstuffs, and other goods, to the beach or camp site location, and then convert the hand truck to a seat where they may sit or rest without the need to bring an additional chair. The device may further collapse down into a compact form factor for ease of transportation.

The present invention relates to stabilization of RNA, in particular mRNA, and an increase in mRNA translation. The present invention particularly relates to a modification of RNA, in particular in vitro-transcribed RNA, resulting in increased transcript stability and/or translation efficiency. According to the invention, it was demonstrated that certain sequences in the 3′-untranslated region (UTR) of an RNA molecule improve stability and translation efficiency.
