The specific embodiment

Referring to Fig. 1, at base 1 and the chair cushion 2 intermediate configurations front and back translating device I and the jacking system II of automotive seat.Front and back translating device I is that the front and back driver train 4 of power drives 7 rotations (each driver train described herein includes motor and retarder) of fore-and-aft adjustment leading screws with the motor-driven, the front and back driver train is fixed on the movable slide rail 10, the corresponding with it translation adjustment nut 8 that is fixed on the base 1 is worked in coordination with fore-and-aft adjustment leading screw 7, impel the 10 front and back translations of fore-and-aft adjustment leading screw 7 drive activity slide rails, movable slide rail 10 slides on the fixed rack 9 that is fixed in base 1, thus chair cushion 2 above driving and backrest 3 whole front and back translations.

Described jacking system II is fixed on the lower shaft 11 of movable slide rail 10, be fixed with lift drive mechanism 5 rotationally, the swing screw mandrel 12 that this lift drive mechanism 5 drives is meshing with each other with the following nut 15 of hinge joint in lower swing plate 14 lower ends, impel following nut 15 to move, when swing screw mandrel 12 rotates, also can turn an angle around lower shaft 11 with the lower end edge swing screw mandrel 12 of lower swing plate 14.Lower swing plate 14 upper ends are fixed on the transmission shaft 16, and transmission shaft 16 is positioned on the movable slide rail 10 by bearing rotationally.Also be fixed with oscillating deck 13 on the transmission shaft 16, last oscillating deck 13 is by hinge joint plate 17, hinge joint on the stay bearing plate 18 under chair cushion 2 front end edge, thereby make chair cushion 2 liftings through transmission shaft 16, the phase mutual interference of inter-agency generation when the purpose of set hinge joint plate 17 is to avoid chair cushion 2 to move forward and backward.The hinge joint of chair cushion 2 back end edge is on movable slide rail 10.In like manner above-mentioned jacking system II commutation can also be connected the back of chair cushion 2, in order to the rear portion of lifting chair cushion 2.For making dipping and heaving stable, can support the both sides of chair cushion 2 front end edge at oscillating deck 13 and hinge joint plate 17 on one of the left and right sides of transmission shaft 16 Bian Geshe.

By Fig. 2, Fig. 3 signal, this technical scheme can be distinguished or the front-end and back-end of lifting chair cushion 2 simultaneously, adjusts more flexibly, is suitable for.Promptly in device shown in Figure 1, a cover jacking system is set at the rear portion of chair cushion 2 again.Directly hinge joint is at last oscillating deck 13A one end to be in the stay bearing plate 18A of chair cushion 2 back end edge, and the last oscillating deck 13A other end is fixed on the transmission shaft 16A, last oscillating deck 13A also can about respectively install 1.Transmission shaft 16A can be rotatably mounted on the movable slide rail 10 with bearing or additive method, also can fix oscillating deck 14A on the transmission shaft 16A, the following nut 15A of lower swing plate 14A lower end hinge joint is engaged on the swing screw mandrel 12A, and the lift drive mechanism that drives swing screw mandrel 12A is rotatably positioned on lower shaft 11 with swing screw mandrel 12A.Long and short dash line shown in Fig. 3 represents that partly upper and lower oscillating deck and following nut are in the scheme drawing of another location with the rotation of swing screw mandrel.

Fig. 4 demonstrates another embodiment that lift drive mechanism 5 and 5A connect with lower shaft 11.Be fixed with two base plates 22 downwards from lower shaft 11, connect front and back two cover lift drive mechanism 5 and the 5A with swing screw mandrel respectively, this two covers lift drive mechanism is installed in rotation on the lower end of respective base 22.The improvement of this embodiment has reduced the installation site of motor and driver train, prevents to hinder when using the big motor of volume the lifting of chair cushion.

As everyone knows, translating device I as herein described and jacking system II preferably are installed in below the chair cushion snugly.In addition, parts that function described herein is identical and power plant etc. can adopt same specification and model, so that processing and manufacturing.

See that Fig. 2, Fig. 3 have also illustrated backrest reclining apparatus III, with backrest driving mechanism 6 is power, driving couple axle 19 rotates, couple axle 19 orders about recliner 20 and rotates, recliner 20 is installed on the side plate 21 of automotive seat, thereby drive backrest 3 and finish angular adjustment, its principle and technology are known not in this explanation for those skilled in the art.

The electric machine control button can be installed in the position that does well out of driver operation during the actual use of the utility model, can reach the purpose of this utility model, not explain at this.
