ROTATABLE VEHICLE SEAT FRAME ASSEMBLY

摘要

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.

1. A rotatable vehicle seat frame assembly comprising:
a main frame; at least one first seat frame mounted on a top surface of the main frame; each one of the at least one first seat frame having
a first stand assembly having
a first base bracket;a first stand slidably mounted on a top surface of the first base bracket; anda first bottom sliding mechanism mounted between the first stand and the first base bracket to make the first stand slidable relative to the first base bracket;a first seat assembly slidably mounted on a top surface of the first stand assembly, and having
a first seat bracket; anda first top sliding mechanism mounted between the first seat bracket and the first stand to make the first seat bracket slidable relative to the first stand; anda first back support assembly pivotally connected to the first seat assembly, and having
a first back support bracket; andat least one first angle-adjusting mechanism mounted between the first back support bracket and the first seat bracket to make the first back support bracket rotatable relative to the first seat bracket; at least one second seat frame mounted on the top surface of the main frame; each one of the at least one second seat frame having
a second stand assembly having
a second base bracket;a second stand slidably mounted on a top surface of the second base bracket; anda second bottom sliding mechanism mounted between the second stand and the second base bracket to make the second stand slidable relative to the second base bracket;a second seat assembly slidably mounted on a top surface of the second stand assembly, and having
a second seat bracket; anda second top sliding mechanism mounted between the second seat bracket and the second stand to make the second seat bracket slidable relative to the second stand;a second back support assembly pivotally connected to the second seat assembly, and having
a second back support bracket; andat least one second angle-adjusting mechanism mounted between the second back support bracket and the second seat bracket to make the second back support bracket rotatable relative to the second seat bracket; anda leg rest assembly pivotally connected to a front side of the second seat bracket, and having
a first leg rest pivotally connected to the front side of the second seat bracket;a second leg rest pivotally connected to a front side of the first leg rest; anda rotating assembly mounted between the first leg rest and the second leg rest to make the second leg rest rotatable relative to the first leg rest; and at least one elevatable desk retractably mounted in the main frame.
