The specific embodiment
Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described in detail.
Like Fig. 1 to shown in Figure 4, the turnover seat underframe of present embodiment, comprise seat support 1, screens mechanism 2, two support 3,4 and two of slide mechanisms and be fixed on the base 5,6 on the vehicle body; Said base 5 is provided with carrier base 51 and supporting seat 52, is formed with draw-in groove 53 between said carrier base 51 and the supporting seat 52, and said carrier base 51 is provided with screens piece 54; Said base 6 is provided with carrier base 61 and supporting seat 62; Be formed with draw-in groove 63 between said carrier base 61 and the supporting seat 62, said carrier base 61 is provided with screens piece 64, and two foots of said seat support 1 are hinged on respectively on the carrier base 51,61; One end of said support slide mechanism 3,4 is hinged on the supporting seat 52,62; Its other end is fixed on the respective side of seat support, and said screens mechanism 2 is movably arranged on the seat support 1, and its support end is pressed on the screens piece 54,64; Its positive stop end sticks in the draw-in groove 53,63, and this positive stop end is connected with the screens switch.
In the present embodiment; Said screens mechanism 2 comprises strut bar 21, position-limited lever 22, left contiguous block 23 and right contiguous block 23; 21 of said strut bars are located on the seat support 1, and said position-limited lever 22 is fixed on the strut bar 21 through left contiguous block 23 with right contiguous block 24 and the two ends of position-limited lever 22 stick in the draw-in groove 53,63, and an end of said position-limited lever 22 is connected with foot-operated switch 25; Said foot-operated switch 25 and strut bar 21 coaxial being located on the seat support 1; Be provided with contiguous block 26 between said strut bar 21 and the position-limited lever 22, be connected with manual draw bar 27 on the said contiguous block 26, make things convenient for the passenger manually to stir seat.Position-limited lever 22 can skid off draw-in groove 53,63 fast when seat need be overturn, and is connected with a spring between position-limited lever 22 and the seat support 1.In order to make mounting safety attractive in appearance, antifriction rubber is installed on the foot-operated switch.
In the present embodiment, because two support slide mechanisms are identical, only describe one at this.Said support slide mechanism 3 comprises fix shaft 31, spring 32, top shoe 33 and fixed block 34, and the lower end of said fix shaft 31 is fixed on the fixed block 34, and top shoe 33 is passed in its upper end; Fix shaft 31 is formed by connecting the round bar of two joint different-diameters, and wherein, the diameter of last pitch circle bar is less than the diameter of following pitch circle bar; Top shoe 33 can slide on last pitch circle bar; Said spring 32 is connected between top shoe 33 and the fixed block 34, and said top shoe 33 is fixed on the seat support 1, and said fixed block 34 is hinged on the supporting rod seat 52; Be provided with setting nut 35 between said spring 32 and the fixed block 34, can carry out fine adjustment the bearing height of seat.In order to make mounting safety attractive in appearance, whole support slide mechanism is equipped with plastic housing.
