Specifically, the driving mechanism is a linear driver and may be a push rod motor, and in this embodiment, only one push rod motor is needed to implement adjustment of the seat between three positions. The motor end of the driving mechanism is connected with the mounting cross rod 6 through a mounting piece, and the push rod end of the driving mechanism is connected with the driving cross rod 7 through a mounting piece.
In particular, fig. 5-7 are three position diagrams of the seat stretching linkage mechanism (thick solid lines in the figures respectively represent the transmission member and the elastic member), and in practical application, the driving mechanism can be controlled by a remote controller or a switch button to drive the seat linkage support structure to adjust in the sitting position, the stretching position and the lying position. When the seat support is adjusted from the sitting posture to the stretching posture, the push rod of the driving mechanism pushes the driving cross rod forwards, the driving cross rod drives the pedal telescopic mechanism 5 to stretch forwards, and the linkage assembly and the backrest mounting piece are kept motionless. When the seat is adjusted from the stretching position to the lying position, the driving mechanism continues to operate the push rod to extend completely, the driving cross rod 7 and the pedal telescopic mechanism 5 are pushed to extend upwards relatively, the seat frame 3 is driven to rotate upwards, the transmission piece 2 is lengthened, and the backrest mounting piece rotates downwards and backwards. When the seat support is adjusted and retracted from the lying position, the seat frame is rotated and retracted downwards under the action of the self gravity of a human body because the head is lifted and the upper body is upright when sitting up, so that the backrest mounting piece 4 is rotated and retracted firstly, and then the pedal telescopic mechanism 5 is retracted. In the lying position, the transmission part 2 tightly pulls the pedal telescopic mechanism, so that the pedal telescopic mechanism is folded and retracted after the backrest mounting part is retracted. The transmission part 2 with elasticity in the process can enable the seat support to be smoother in the position adjusting process, and meanwhile, the transmission part 2 ensures the movement sequence of the backrest installation part and the pedal telescopic mechanism in the unfolding and the retracting of the seat.
Specifically, as shown in fig. 8, the seat support of the present invention is fixed in the armrest frames at both sides of the seat, and is manufactured into a sofa or a leisure seat by installing the armrest frame 200, the backrest frame 400 and the seat frame and then soft-packing the upholstery. It should be noted that, the assembly plate of the present embodiment is connected to the armrest frame and is fixed, and the backrest frame 400 may be configured as a T-shaped frame when viewed from the front of the seat, so that two protruding ends of the T-shaped backrest frame do not interfere with the armrest frame, and the T-shaped backrest frame 400 may rotate around the armrest frame 200.
As shown in FIG. 9, the seat support of the present invention has fewer parts of the linkage assembly than the original seat support, the backrest assembly is optimized to have only one backrest mounting member, and the seat support is significantly reduced in height, as shown by the greater than 2cm in height dimension compression. The invention optimally simplifies the structure of the seat stretching linkage mechanism, compresses the whole height of the seat support, reduces the production cost, ensures that the seat is more stable and smooth when being retracted from the lying position by connecting the pedal telescopic mechanism and the linkage assembly through the transmission piece, and improves the comfort level of the seat.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are in no way limiting of the invention. Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
