detailed description

The exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Not all embodiments are exhaustive. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

The core idea of this application is to integrate the space occupied by the passenger's calf and foot into the seat space during the use of the conventional business seat without affecting the overall seat footprint, so as to save more use. Space, increase the train capacity; at the same time, according to the structure of the new business seat, reconfigure the seat accessories to facilitate the use of passengers.

The embodiment of the present application provides a business seat including: a sitting shifting seat; the sitting shifting seat is disposed in the vehicle at a predetermined angle away from the traveling direction of the vehicle. Further, as shown in FIG. 1 and FIG. 2, the embodiment of the present application provides another commercial seat, including: two sitting-to-converter seats arranged in parallel; each sitting shifting seat is offset from the vehicle by a predetermined angle. The direction of travel is disposed within the vehicle; the two sitting shifting seats are offset in opposite directions. Among them, the front sides of the two sitting conversion seats are close to each other, and the rear sides are away from each other. The scheme utilizes the idea of spatial multiplexing, and in the lying position, the calf and/or foot space of the rear passengers is merged into the space deviated between the front seat and the traveling direction of the vehicle, thereby reducing the lying position. The space occupied by passengers in the state and the spatial multiplexing of the front seats. In the present solution, the predetermined angle ranges from 10 degrees to 35 degrees. Preferred angles are 15 degrees, 20 degrees and 25 degrees.

In the present solution, the sitting conversion seat includes: a seat frame 1, a backrest 9 and a seat cushion 8; as shown in FIGS. 1 and 2, the backrest 9 and the seat cushion 8 are half wrapped in the seat frame 1 The backrest 9 and the seat cushion 8 are interlocked with each other by a skeleton mechanical structure such as a link structure. The seat cushion 8 is disposed on the seat frame 1 by a sitting conversion mechanism. Further, a groove 11 for accommodating the backrest 9 is provided on the seat frame 1 at a position of the backrest 9, and the arrangement of the groove 11 can further provide a conversion space for the sitting conversion.

In the present solution, the sitting conversion mechanism includes: a pair of slide rails disposed on the seat frame 1, and a third-order guide rail and a motor fixed on the seat cushion respectively disposed in the slide rail. Wherein, the motor is directly fixed on the seat frame 1, and the seat cushion 8 is reciprocated in the slide rail by the cooperation of the third-order guide rail and the ball; since the seat cushion 8 and the backrest 9 are linked by the link mechanism, the backrest 9 is also The seat cushion 8 is moved together, and at the same time rotated relative to the seat cushion 8, thereby completing the lifting movement of the backrest 9, thereby realizing the sitting and lying conversion of the seat. In this solution, the angle of the sitting conversion is in the range of 90-180 degrees, and the preferred angle in the lying position is 170 degrees.

In order to further improve the space utilization, in some optional implementation manners of the embodiment, a table box 2 is disposed on one side of the sitting conversion seat, and the table box 2 can be independently set in the seat and the vehicle. The gap in the direction may also be fixedly connected to the seat 1; the opening direction of the table box 2 is opposite to the traveling direction of the vehicle. The table box 2 can be made into an integrated structure or a split structure according to the processing technology or the installation requirements. When the two sitting shifting seats are arranged side by side, the inside of the two seats deviating from the traveling direction of the vehicle may each be provided with a table box 2; the opening direction of the table box 2 is opposite to the traveling direction of the vehicle. The two table boxes 2 can be formed into an integrated structure or a split structure with the seat frame 1 depending on the processing technology or installation requirements. A further preferred solution is to use the two table boxes 2 and the chair frame 1 as a unitary structure, and at the same time, in order to prevent the mutual collision of the foot portions between the passengers, the partition plate in the center of the integrated table box 2 is used by the partition plate. The integrated table box is divided into two spaces, which are used by two passengers separately. In the present solution, another function of the table box 2 is to serve as a table for the passenger's goods, which can satisfy the passenger to place the belongings or other items on the upper surface of the table box 2, and not only the seat for further use and the direction of travel of the vehicle. Space, while providing more convenience for passengers.
