Correspondingly close to the first magnet pieces 37B.The adsorption capacity between the second magnet pieces 38B and the first magnet pieces 37B makes cross bar as a result,
Guide part 36 is applied with the trend power towards 32 direction of support plate in support rail portion 331.Support rail portion 331 is solving
It is moved under lock status at gear slot 341 and when solution lock section 351 is released, which just drives support rail portion 331 to leaning on
The direction of nearly support plate 32 is mobile hence into gear slot 341, that is, enters corresponding support gear.
Below in conjunction with attached drawing, using for the adjustable waist support 100 of the present embodiment is illustrated for being applied to automotive seat
Journey and working principle.
It when using adjustable waist support 100, first rotates the first fixed plate 21 and the second plate portion 212 is allowed to turn to rear side, then will
Automotive seat is leaned against in gap between the second plate portion 212 insertion backrest and cushion and by the rear side surface of the second fixed plate 22
Lean on back.It is then possible to buttress the second fixed plate 22 on the other hand, the other hand pulls up or is pressed downward waist panel 10, makes on substrate 31
Bump portion be moved in one group of hole portion 223 appropriate, thus allow waist panel 10 in above-below direction be located at suitable position (be located at
Suitable height), it completes height and adjusts.
After user sits to automotive seat, hand backhand can be reached behind pin press section 352 and (pin pressing tablet
3521) it, allows support rail portion 331 to be lifted and be detached from gear slot 341, realizes unlock.Then, user can rotate waist panel
10, it adjusts to suitable angle position (such as the position for allowing waist panel 10 to be bonded with waist) and unclamps press section 352 afterwards, then slightly turn
Dynamic adjustment waist panel 10 allows under adsorption force of the support rail portion 331 between the second magnet pieces 38B and the first magnet pieces 37B
Into apart from nearest gear slot 341, that is, complete the adjustment of support gear.In addition, if user supports when unclamping press section 352
Cross bar portion 331 has moved at the position of top side, then user, which slightly adjusts waist panel 10, will not allow support rail portion 331
Into gear slot 341；At this point, the power that waist is pressed on waist panel 10 will make to support if user leans against waist on waist panel 10
Plate 32 generates the trend rotated slightly backward, moves support rail portion 331 slightly upwardly relative to support plate 32 and is connected to shelves
Position forms the inner top side of part 34, and support plate 32 is supported on support gear corresponding to the inner top side.
In the present embodiment, the first magnet pieces 37B has certain thickness, when support rail portion 331 is located in groove 341,
