Abstract: A folding table and chair device has a chair assembly and a table assembly. The chair assembly has a supporting bracket, a seat mounted securely on a top of the supporting bracket, a backrest mounted pivotally on a rear end of the seat, and a footrest mounted pivotally on a front end of the seat and being capable of pivoting forward to a horizontal position. The table assembly is mounted in front of the chair assembly and has a wall board mounted in front of the chair assembly, and a folding table mounted pivotally on the rear of the wall board and being capable of pivoting downward to a horizontal position. The folding table and chair device allows a user to lie completely down thereon.

Abstract: A rotatable vehicle seat frame assembly has a main frame, at least one first seat frame, at least one second seat frame, and at least one elevatable desk. Each seat frame has a bottom sliding mechanism, a top sliding mechanism, and an angle-adjusting mechanism. The second seat frame further has a leg rest assembly. The bottom sliding mechanisms, the top sliding mechanisms, the angle-adjusting mechanisms, and the leg rest assembly enable the seat frame to be rotated into a flattened status in a limited inner space of a vehicle, enable the seat frame to be transformed between a passenger-mode and a cargo-mode, and enable the seat frame to be used as a bed during a long trip. When in the passenger-mode, the position of the seat bracket and the angle of the back support bracket may be adjusted to facilitate convenience, and to provide more use modes in a limited inner space with the elevatable desk.

Abstract: A foldable leg rest has a seat, a folding frame and a drive mechanism. The folding frame is pivotally connected to the seat. The drive mechanism includes a first actuator and a second actuator. The first actuator has a front end and a rear end. The front end of the first actuator is pivotally connected to the folding frame. The second actuator has a front end and a rear end. The rear end of the second actuator is pivotally connected to the seat. The front end of the second actuator is secured to the rear end of the first actuator. The first actuator and the second actuator are actuated to pivot the folding frame to a horizontal plane in which the seat lies.

Abstract: A foldable leg rest has a seat, a first folding frame and a first stage drive mechanism. The first folding frame is pivotally connected to the seat. The first stage drive mechanism includes two angle adjusters, two first stage DC motors and a drive rod. Each of the angle adjusters is disposed between one of opposite sides of the seat and one of opposite sides of the first folding frame. The first stage DC motors are respectively disposed on the sides of the seat. The drive rod is connected between the angle adjusters. In use, the first stage DC motors are actuated to drive the drive rod and the angle adjusters such that the first folding frame is pivoted relative to the seat.

Abstract: A rotatable vehicle seat frame has a base bracket, a stand, a seat bracket and a back support bracket in sequence from up to down. A bottom sliding mechanism is mounted between the base bracket and the stand. A top sliding mechanism is mounted between the stand and the seat bracket. An angle-adjusting mechanism is mounted between the seat bracket and the back support bracket. The mechanisms mentioned above enable the rotatable vehicle seat frame to be rotated and transformed between a passenger-mode and a cargo-mode. Multiple rotatable vehicle seat frames with a frame and an elevatable desk form a rotatable vehicle seat frame assembly to be further applied in various kinds of vehicles.

Abstract: A multi-functional table and chair device has a base, two opposite chair sets mounted on the base, and an adjustable table. Each chair set has at least one chair, and each chair has a supporting bracket, a seat, a backrest and a footrest. The adjustable table is mounted on the base between the chair sets and has a bottom bracket, an elevation mechanism and a table board. When the backrest of one chair is pivoted backward and the footrest is unfolded, the chair is changed into a deck chair. When the footrests of two opposite chairs of the chair sets are pivoted upward and unfolded to be horizontal and the adjustable table is raised to hold the footrests, the two opposite chairs and the adjustable table form a bed.

Abstract: A foldable leg rest has a slide base, a first folding assembly, a second folding assembly, a first stage drive mechanism and a second stage drive mechanism. The slide base has a slide frame. The first folding assembly has a first frame pivotally connected to the slide frame. The second folding assembly has a second frame pivotally connected to the first frame. In use, the first stage drive mechanism is operated to drive the first frame to pivot relative to the slide frame and the second stage drive mechanism is operated to drive the second frame to pivot relative to the first frame. Therefore, the legs of a sitter can be stretched and placed on the folding assemblies so as to enhance comfort and minimize fatigue.
