It sets the backrest sliding block 32 in area, backrest body 31 and backrest sliding block 32 to connect by the second sliding equipment 5, the second sliding equipment 5 packet
Second for including the second sliding slot 51 that two opposite insides in the vacant area are arranged in and being set to 32 liang of outsides of backrest sliding block is sliding
First 52, the second slippery fellow 52 is slidably fixed in second sliding slot 51.
Based on this, the present embodiment also has better effect.The back of user is contacted with backrest sliding block 32, and sitting posture is adjusted
When, although opposite change in location can occur relative to back for backrest 32, since backrest sliding block 32 and backrest body 31 pass through
The connection of second sliding equipment 5, therefore, variation of the back of user with hardly happening relative position between backrest sliding block 32.
This relatively-stationary mode, be conducive to adjust goes on smoothly, and otherwise this opposite variation will occur at back and lean on
Between back, certain obstruction will be generated to adjusting, need user that the upper part of the body is lifted or used slightly using waist abdomen strength
Arm strength is propped up above the waist, could further adjusting sitting posture.
In the present embodiment, as shown in figure 4, being provided with locking mechanism 8 between fixing slide carriage 41 and sliding shoe 42, machine is locked
The bolt 81 and the multistage pin being arranged corresponding with bolt 81 on fixing slide carriage 41 is set that structure 8 includes and sliding shoe 42 links
Hole 82.It further include the control mechanism 9 of bolt, the control mechanism 9 of bolt includes for accommodating lock bolt cylinder 91, being arranged in pin cylinder
The interior spring 92 for resetting bolt and the bracing wire 93 for controlling bolt；When bracing wire 93 is pulled, bolt 81 is from pin
Hole 82 is drawn off so that sliding shoe 42 relative to fixing slide carriage 41 slidably；When bracing wire 93 is not drawn, sliding shoe 42 is moved to
When suitable position, spring 92 resets bolt, and bolt end is inserted into pin hole 82, makes sliding shoe 42 relative to the fixing slide carriage
41 is fixed.
