The purpose of this utility model is achieved in that a kind of seat Waist protection pad adjusting device, it is characterized in that: described Waist protection pad adjusting device comprises the support that is installed in the backrest rear portion, rack-mount and drive the screw mandrel displacement mechanism that Waist protection pad moves forward and backward.
Described screw mandrel displacement mechanism mainly comprises adjusting knob, is fixed on the positioning and guiding sleeve on the support, the external screw thread screw mandrel that is flush-mounted in the movable screw mandrel of internal thread in the positioning and guiding sleeve and is connected with the screw-internal thread fit of the movable screw mandrel of internal thread, wherein, the positioning and guiding sleeve lining is provided with and stops movable screw mandrel rotation of internal thread and the guide rail parallel with the shaft core line of its positioning and guiding sleeve, the movable screw mandrel lateral wall of internal thread is provided with the gathering sill that matches with guide rail, and the movable screw mandrel of this internal thread can move forward and backward in the positioning and guiding sleeve along the guide rail direction; Described positioning and guiding cover tube bottom has through hole, and adjusting knob is positioned at positioning and guiding sleeve outer end and is connected with the external screw thread screw mandrel of positioning and guiding sleeve by through hole; Described internal thread movable wire is connected with Waist protection pad with bar.
Described adjusting knob is provided with flange, and the end that the external screw thread screw mandrel is connected with adjusting knob is provided with boss, and this raised head face offers groove; Through hole rearward recess and flange that boss passes the positioning and guiding sleeve match, and are fastenedly connected by screw again.
Described adjusting knob lateral wall is provided with waveform friction striped.
The movable screw mandrel of described internal thread is hinged on the back side of Waist protection pad.
Good effect of the present utility model: a manually operated screw mandrel displacement mechanism is installed in the back bracket back, front and back position by mechanical transmission mechanism control backrest Waist protection pad, simple in structure, adopt the backrest Waist protection pad adjusting device of airbag aeration control mode or electronic control mode relatively, operation is very easy, can effectively reduce production cost.
As further improvement of the utility model, the movable screw mandrel of internal thread is hinged on the back side of Waist protection pad, Waist protection pad just has the ergonomics function that " chases after the back of the body " like this, if the power that applies on Waist protection pad, this Waist protection pad can be adjusted angle automatically according to the direction of power.That is to say, can slow down fatigue along with docile and obedient user's health at any time such as people's the sitting posture and the height of vertebra waist song.

The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is elaborated.
Embodiment: shown in Fig. 1-6: seat Waist protection pad adjusting device described in the utility model, mainly form by support 1, screw mandrel displacement mechanism 2.Support 1 is installed in backrest 3 rear portions, screw mandrel displacement mechanism 2 is installed on the support 1 and with Waist protection pad 30 and is connected, variable in distance by screw mandrel displacement mechanism 2 can drive Waist protection pad 30 and move before and after on backrest 3, satisfies the different sitting posture needs of people, reaches healthy comfortable effect.Screw mandrel displacement mechanism 2 mainly by adjusting knob 4, be fixed on the movable screw mandrel 6 of positioning and guiding sleeve 5, internal thread on the support 1 and form than the external screw thread screw mandrel 7 that line 60 is connected with the interior spiral shell of the movable screw mandrel 6 of internal thread, wherein, the bottom of positioning and guiding sleeve 5 has a through hole, adjusting knob 4 is positioned at positioning and guiding sleeve 5 outer ends, is provided with flange 40 on one end.External screw thread screw mandrel 7 is installed in the positioning and guiding sleeve 5, and the end that external screw thread screw mandrel 7 is connected with adjusting knob 4 is provided with boss 70, and these boss 70 end faces offer groove 700; Through hole rearward recess 700 and flange 40 that boss 70 passes positioning and guiding sleeve 5 match, the center of adjusting knob 4, external screw thread screw mandrel 7 has screwed hole, after flange 40, groove 70 cooperate, by screw 8 adjusting knob 4, external screw thread screw mandrel 7 are fastenedly connected, like this, when turning adjusting knob 4, external screw thread screw mandrel 7 is rotation synchronously, and adjusting knob 4, external screw thread screw mandrel 7 can also adopt connected modes such as sleeve alignment pin certainly.Positioning and guiding sleeve 5 inwalls are provided with and stop movable screw mandrel 6 rotation and the guide rails 50 parallel with the shaft core line of its positioning and guiding sleeve 5 of internal thread, movable screw mandrel 6 lateral walls of internal thread are provided with the gathering sill 61 that matches with guide rail 50, and the movable screw mandrel 6 of internal thread can move forward and backward in positioning and guiding sleeve 5 along guide rail 50 directions.Installation process is as follows, the gathering sill 61 of the movable screw mandrel 6 of internal thread is aimed at the guide rail 50 of positioning and guiding sleeve 5 inwalls, twist adjusting knob 4, and then rotation of external screw thread screw mandrel 7, because the external screw thread 71 of external screw thread screw mandrel 7 is connected with the internal thread 60 of the movable screw mandrel 6 of internal thread, and the movable screw mandrel 6 of internal thread is by guide rail 50 restriction rotations, only in guide rail 50, move forward and backward, when the gathering sill 61 of the movable screw mandrel 6 of internal thread enters when being connected in the guide rail 50, the movable screw mandrel 6 of internal thread has promptly installed, continue to turn adjusting knob 4, the movable screw mandrel 6 of internal thread will be to the inner end indentation of internal thread movable wire bar 6; Otherwise, then withdraw from, because the other end of the movable screw mandrel 6 of internal thread and the rear portion of Waist protection pad 30 are hinged, therefore, moving of the movable screw mandrel 6 of internal thread promptly driven moving of Waist protection pad 30, so just realized regulating the purpose of the front and back position of Waist protection pad 30, structure is very simple, and easy to operate, and all action is manually finished.In order to be easier to turn adjusting knob 4, be provided with waveform friction striped 41 at its lateral wall, increase the frictional resistance that contacts with hand.
