As shown in Figure 5, the chair regulating device of the utility model preferred embodiment comprises the saturating empty rectangle pedestal 4 in a bottom, these pedestal 4 front ends are provided with a perforation 41, and the top, front and back end has protruded out a stator 42 toward each level of both sides, respectively is provided with a fixing hole 421 on each stator 42.Pedestal 4 bottom vertical down convex with two pairs of

lugs

43,43 ', 43 of lugs borrow a latch 431 to connect a pedestal part 44.These pedestal 4 rear ends utilize a pivot 45 back seat portion 46 that is pivoted.The perforation 41 of pedestal 4 front ends is provided with one can make the seat cushion and the chair back produce elasticity simultaneously to swinging back to the pendulous device 5 of lying.

Vertically be provided with on this pedestal part 44 coupling hole 441 and oval hole 441 ', be equipped with a height adjusting link 442 on the sidewall, be provided with one first adjusting device 6 near these height adjusting link 442 places, this first adjusting device 6 has a scarfing seat 63, a sheathed screw rod 61 and a spring 62 that is placed through on the screw rod 61 in this scarfing seat 63, this scarfing seat 63 is embedded on these pedestal part 44 side wall surfaces.This scarfing seat 63 is provided with a pair of pivot ear 631 in these pedestal part 44 lateral wall places, and pivot ear 631 borrows a latch 632 that a throw rod 64 is hubbed on this scarfing seat 63, and there is a convex globoidal 641 end of this throw rod 64.Wear an end and the packing ring 71 of the seat cushion trimmer 7 that is provided with at interval on the screw rod 61 of this first adjusting device 6, the other end of this seat cushion trimmer 7 by means of a latch 72 be fixedly arranged on the lug 43 of pedestal 4 ' on.

This back seat portion 46 vertically forms a saturating dead slot 461, these pedestal 4 sidewalls are equipped with one second adjusting device 8 near these back seat portion 46 places, the structure of this second adjusting device 8 is identical with first adjusting device 6 haply, also pass an end and the packing ring 91 of the chair back trimmer 9 that is provided with at interval on it, these chair back trimmer 9 other ends are hubbed in this back seat portion 46.The scarfing seat 63 of this second adjusting device ' on also be pivoted with a throw rod 81, as shown in Figure 6, these throw rod 81 ends also form a convex globoidal 811.This pendulous device 5 comprises that a retaining element 51, flexible member 52, pad 53 and bottom are provided with the cup 54 of screw, in the present embodiment, this retaining element 51 is the screw rod 51 that an end has screw thread, this flexible member 52 is a spring 52, this screw rod 51 is from the perforation 41 of these pedestal 4 front ends and the hole 441 of pedestal part 44 ' pass, and passes this spring 52 and pad 53 and spiral shell in regular turn and be located in the screw of cup 54 bottoms.By adjusting the weight that is spirally connected between these screw rod 51 ends and these cup 54 screws, can control spring 52 clampings of 44 of this cup 54 and pedestal part or loosen, the size of temporarily transferring whole spring 52 bounces can change with seat cushion and the chair back toward layback lie the application of force size of palpus.

When desire is assembled in the utility model on the seat support, shown in Fig. 5,7, fixing hole on the stator 42 421 is installed in pedestal 4 below of a seat cushion 91, coupling hole on the pedestal part 44 441 is sheathed on the foot rest 92 of seat, chairback brace 93 is installed in the saturating dead slot 461 of this back seat portion 46 again, has just finished assembling.

Shown in Fig. 5,6,7, in the time will adjusting the angle of inclination of seat cushion 91, the throw rod 64 of first adjusting device 6 is up pulled, make the ora terminalis of its convex globoidal 641 contact screw rods 61, to offset the skew clamping power that this seat cushion trimmer 7 is caused because of packing ring 71, make this seat cushion trimmer 7 be loose shape and be connected with

latch

72,61 of screw rods, the latch 431 that the pedestal 4 that then is located at seat cushion 91 belows just can itself and pedestal part 44 articulates tilts forward and back with the adjustment angle of inclination for the axle center.After being adjusted to suitable angle, turn back this throw rod 64, then this seat cushion trimmer 7 is borrowed its biasing force and is recovered blocking to 61 of this latches 72, screw rod, and 4 of this base 44 and pedestals are securely engaged.In the same manner, the adjustment at chair back angle of inclination also is earlier the throw rod 81 of second adjusting device 8 up to be pulled, after the skew clamping power that this chair back trimmer 9 and packing ring 91 are caused is offset, the pivots 45 that back seat portion 46 is articulated mutually with itself and pedestal 4 are that the axle center tilts forward and back and adjusts the angle of inclination, after being adjusted to suitable angle, it is just passable to turn back this throw rod 81 again.

This usefulness is novel to be made the seat cushion and the chair back reach the effect that elasticity lies to layback simultaneously to be described as follows.

As shown in Figure 8, this seat cushion 91 can be an axis swing by the latch 431 that articulates this pedestal 4 and pedestal part 44 with the chair back 93, when the user executes a strength backward and presses on the chair back 93, the screw rod 51 that is located at pedestal 4 front ends below can up be spurred by this pedestal 4, and, oval hole 441 on this pedestal part 44 ', the cup 54 that this screw rod 51 can be located at spiral shell produces the strength toward the pulling that tilts, then the spring 52 in this cup 54 can be subjected to this cup 54 up to be closely against bounce of bottom generation of pedestal part 44, if the user loosens the strength that this chair back 93 is pressed, spring 52 stored bounces will make this seat cushion 91 return back to original position with the chair back 93 naturally with these screw rod 51 pulled down.In addition, by adjusting the weight that is spirally connected between these screw rod 51 ends and these cup 54 screws, can control the relative position of this cup 54 and pedestal part 44,, just can adjust this seat cushion 91 press required strength backward with the chair back 93 with in addition clamping or loosen of therebetween spring 52.

By upper explanation as can be known, the utility model ratio seat adjusting device in the past has following advantage:

1. function is more complete:

The utility model is the angle of inclination of capable of regulating cushion 91 and the chair back 93 not only, more can make seat cushion 91 and the chair back 93 produce simultaneously elasticity and lie to layback, and function ratio is in the past complete.

2. use upper more convenient comfortable:

The utility model is adjusted seat cushion 91 and is provided with the device at the chair back 93 angles of inclination is independent respectively, so when adjusting the angle of inclination of the seat cushion 91 or the chair back 93, can not interfere with each other, and the user can arbitrarily adjust the size of facing upward lie seat cushion 91 and the chair back 93 required application of forces, and is more more convenient more comfortable than in the past in the use.

In sum, chair regulating device of the present utility model, inconvenience can be adjusted the angle that tilts forward and back of the seat cushion and the chair back respectively, also can make the seat cushion and the chair back do elasticity simultaneously and lie to layback, and is more convenient comfortable in the use.
