Abstract
The invention relates to a seat back adjusting mechanism. The seat back adjusting mechanism comprises chair back frames, air springs, locking units and chair seat frames. One ends of the air springs are connected with the chair back frames, and the other ends of the air springs are connected with chair seat frames; one ends of the locking units are connected with the chair back frames, and the other ends of the locking units are in pin connection with the chair seat frames; each locking unit comprises a steel ball, a pressing block, a steel cable, an adjusting rod, a lock frame, a convex head and a pressure spring; the convex heads are arranged in the lock frames; and the right ends of the convex heads are sleeved with the pressure springs, and the left ends of the convex heads are in contact with the steel balls. The adjusting rods penetrate through holes of the convex heads, and a plurality of grooves are formed in each adjusting rod; and the steel balls are clamped between the lock frames and the rear ends of the pressing blocks, and the steel cables are arranged at the front ends of the pressing blocks. The adjusting mechanism is small in size, reliable in performance and convenient to maintain. When other parts need to be installed on the rotating position of a seat back or an angular adjuster cannot be mounted, the back adjusting mechanism can be used.
Description
Technical field
The present invention relates to seat, more particularly, relate to a kind of Seat back modulating mechanism.
Background technology
Aircraft seat mainly adopts recliner to realize backrest regulatory function both at home and abroad at present, this kind of recliner carrys out adjusting angle by handle and handwheel, volume is larger, and connection rotation place of the chair back and base must be arranged on, for rotation place narrow space or when needing to install other parts, this type of recliner just can not meet the requirement of seat design.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of Seat back modulating mechanism that can be arranged on nonrotational place.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of Seat back modulating mechanism, comprise chair back rack, gas spring, lock cell, chair seat frame, one end of gas spring is connected with chair back rack, the other end is connected with chair seat frame, one end of lock cell is connected with chair back rack, and the other end is connected with chair seat frame pin; Described lock cell comprises steel ball, briquetting, cable wire, adjust bar, lock frame, convex head, stage clip, described convex head is contained in lock frame, and the right-hand member cover of convex head has stage clip, and left end contacts with steel ball, adjust bar is through the through hole of convex head, and described adjust bar is provided with multiple groove; Steel ball is stuck between lock frame and the rear end of briquetting, and cable wire is equipped with in the front end of briquetting.
In such scheme, described chair back rack is connected with balustrade panel, and described balustrade panel is also connected by screw with chair seat frame.
In such scheme, one end of described gas spring is connected by pin with chair back rack, and the other end is connected by pin with chair seat frame,
In such scheme, one end of described lock cell is connected by pin with chair back rack 1, and the other end is connected by pin with chair seat frame.
Implement Seat back modulating mechanism of the present invention, there is following beneficial effect:
Backrest regulating mechanism structure of the present invention is simple, easy to operate, also solve the problem needing handwheel or long distance handle when back of seat regulates simultaneously, miniature lever or button can be used to carry out adjusting angle, and this kind of structure can be arranged on the rear portion of the chair back, does not need rotation place being arranged on the chair back, solve the problem that rotation place can not install recliner, this regulating mechanism compact conformation, connection and reasonable arrangement, use safety is comfortable.Meet the requirement of client to outward appearance and function.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of Seat back modulating mechanism of the present invention;
Fig. 2 is the structural representation of lock cell;
Fig. 3 is the cutaway view of lock cell.
Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1, Seat back modulating mechanism of the present invention comprises chair back rack 1, gas spring 2, lock cell 3, balustrade panel 4, chair seat frame 5.
Chair back rack 1 is connected on balustrade panel 4, balustrade panel 4 and chair seat frame 5 are connected by screw, and one end of gas spring 2 is carried out pin with chair back rack 1 and is connected, and the other end carries out pin with chair seat frame 5 and is connected, one end of lock cell 3 is carried out pin with chair back rack 1 and is connected, and the other end carries out pin with chair seat frame 5 and is connected.
As shown in Figure 2 and Figure 3, above-mentioned lock cell 3 comprises steel ball 6, briquetting 7, cable wire 8, adjust bar 9, lock frame 10, convex head 11, stage clip 12, convex head 11 is contained in lock frame 10, the right-hand member cover of convex head 11 has stage clip 12, left end contacts with steel ball 6, have through hole in the middle of convex head 11, adjust bar 9 is through the through hole of convex head 11, and adjust bar 9 has many grooves; Steel ball 6 is stuck between lock frame 10 and the rear end of briquetting 7, and cable wire 8 is equipped with in the front end of briquetting 7.
During work, cable wire 8 is pulled to drive briquetting 7, under the pressure of briquetting 7, steel ball 6 is to right translation, steel ball 6 contacts with convex head 11, and steel ball 6 promotes convex head 11 to right translation, causes the plush copper of convex head 11 and the groove of adjust bar 9 to depart from, while departing from, stage clip 12 is in compressive state, now completes unblock.After unblock, gas spring 2 gives chair back rack 2 corresponding bearing force, after chair back rack 2 is adjusted to comfortable position, unclamp cable wire 8, be in stage clip 12 resilience of compressive state, promote convex head 11 plush copper and adjust bar 9 groove card with, complete the locking of chair back rack 2, complete the adjustment of passenger to backrest.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
