The beneficial effects of the utility model are:
The mode that drives hinged cross connecting rod and slide rail with backguy obtains two speed simultaneously and drives thigh stay bearing plate and face cover respectively, realizes that depth of seat cushion does not have the gap regulatory function, improves driver leg and supports.Since adopt parts simple, novelty, cost is lower, and assembling form is comparatively convenient simultaneously.
Description of drawings
Fig. 1 is the state that shows of Chain cushion length adjustment mechanism.
Fig. 2 is the maximal regulated state of Chain cushion length adjustment mechanism.
Fig. 3 is the decomposition view of Chain cushion length adjustment mechanism.
Fig. 4 is the scheme drawing that thigh stay bearing plate, face are enclosed within the relative position relation in the seat.
Fig. 5 is the movement relation figure of Chain cushion length adjustment mechanism.
The specific embodiment
As shown in Figure 1 to Figure 3, utilize motor 18 to drive backguy 17 (also can adopt the handwheel manual drives), pulling drive spindle S. A. 7, drive spindle S. A. 7 connects the center of slide rail drive spindle 6 and the pivotally attached center of connecting rod 10 and connecting rod 11 simultaneously.Drive spindle S. A. 7 drives slide rail drive spindle 6 drive slide rails 5 and travels forward, and slide rail 5 moves forward by connecting support 2 driving thigh stay bearing plates 1 again.Two slide rails 5 are arranged on the sliding rail rack 12.
Simultaneously, the center of connecting rod 10 and connecting rod 11 is hinged, and the upper end of the two (front end) joins slidably by top shoe 9 chute with face cover adapter plate 8, and lower end (rear end) is arranged in the gliding groove that Location guide 14 provides by sliding block 13 and joins slidably with Location guide 14.The pivotally attached center-point of drive spindle S. A. 7 drive link 10 and connecting rod 11 travels forward, the sliding block 13 that is connected connecting rod 10 and connecting rod 11 rear ends is along Location guide 14 move toward one another, and the top shoe 9 that is connected connecting rod 10 and connecting rod 11 front ends can slide in the chute of face cover adapter plate 8 and drive surface cover adapter plate moves forward.In the identical time, the distance that thigh stay bearing plate and face cover adapter plate move forward is respectively s1 and s2, s2=2s1.
As shown in Figure 4, Chain cushion foam and face cover 21 are walked around thigh stay bearing plate 1 front end and are fixed on the face cover adapter plate 8, thigh stay bearing plate 1 is when adjustable range is s forward, upper and lower surface face cover 21 all will be regulated s forward, so face cover adapter plate 8 moves forward distance and should be 2s, ability assurance face cover 21 can tension and wrinkling.
As shown in Figure 5, solid line is depicted as the design point position, and dotted line is the maximum position adjustment state, and arrow A indicates cushion and regulates direction.
The o point is a drive point, move to o ' point along direction as shown, because bar ad is consistent with bc length, in motion process, can not change and hinged at point midway (o point), so when the o point when direction as shown is moved, bar ad and bc relatively rotate around the o point, A point and b point move to a ' and b ' along the ab line respectively, simultaneously, c point and d point on bar cd, slide and catch bar cd move to position shown in the c ' d '.
