Background technology

In current state of the art, there is leaning on designed for mobile upholstered furniture (such as sofa or armchair) The mechanism of the back of the body and headrest, but they all there are problems that.

The main problem of existing mechanism is that they require the design of upholstered furniture to have specific shape, they are especially stupid Again and a considerable amount of material is needed to realize；It will continue to make these aspects clearer in the present specification.

First, and with reference to Fig. 1, it is noted that in general, for beautiful and ergonomic reasons, high quality it is soft With padding 1 constructivity of furniture there are 11 (each is different from another) of backrest 10 and headrest, but both are bonded together with shape Into single main body.

The headrest 11 of these types produces semi-circular movement as shown in Figure 1A, so as to from it is horizontal, parallel to seat 13 " closing " change in location in " opening " position at seat 13, pass through therebetween to quite vertical, vertical (or nearly vertical) All centre positions.

Referring again to Fig. 1, the upholstered furniture 1 of high quality includes --- except the backrest 10 of swaying, the moving head Outside pillow 11 and the seat 13 --- extendible foot-operated 12, wherein the headrest 11 and described foot-operated 12 is in " closing " position Put and backrest 10 be in relative to seat 13 vertical position, i.e., in seated position.

With reference to Fig. 2, the identical upholstered furniture 1 in extended position or release position is shown, and it makes 11 liters of headrest Rise, backrest 10 tilts and foot-operated 12 extension, extension.

In the upholstered furniture 1, the movement of three above-mentioned components --- backrest 10, headrest 11 and foot-operated 12 --- is mutual Connection so that the movement of a component follows the movement of other components, to ensure the comfort level of maximum and best suit ergonomic The sitting posture of user U.

According to foregoing, when user U determines extension foot-operated 12, it is set to be extended to from " closing " position (as shown in Figure 1) When stretching position (as shown in Figure 2), backrest 10 also tilts and inevitably moves forward seat 13：As described above, this be for Ensure the maximal comfort of user U；It is worth noting that, in theory, it can be envisaged that allow foot-operated 12 extension and do not have to Reclinable back-rest 10, therefore it is not required seat 13 to move forward, but user U will be in unnatural and uncomfortable position, this Kind position will not last very long.

The elongation of disciplinarian request user's leg of ergonomics is loosened downwards with user back；In addition, it is Make the user U more comfortable, when foot-operated 12 extension and when backrest 10 tilts, the cushion elements of in the market existing furniture Possibility (as shown in Figure 2) usually with " rise " headrest 11, wants to keep him or she to put from semisupination in user U Head it is upright in the case of, provide support for the head of user, so as to perform such as read books or watch TV work It is dynamic, or simply prevent head from hanging down.

For the sake of clarity, all the above are used to more fully understand the present invention, and the present invention is described more fully below, and And it is limited to the upholstered furniture with extensible foot-operated, reclinable back-rest and headrest adjustable.

The operator scheme with the cushion elements of known furniture 1 exists in the prior art in description below, which is equipped with What is intemperated with one another may extend away foot-operated 12, reclinable back-rest 10 and headrest adjustable 11, Fig. 1 and Fig. 2 as has been shown.Institute In the cushion elements for stating furniture 1, control the mechanism of foot-operated 12 movement must be with the machine for the movement for adjusting the backrest 10 Structure couples so that for ergonomic reasons, foot-operated 12 startup needs travelling forward for seat 13, and therefore leans on The back of the body 10 travels forward with headrest 11.

Above-mentioned legacy system has some unfavorable critical aspects：Structurally, the lower part 14 of the cushion elements of furniture 1 Separation between the rear portion 15 of backrest 10 is necessary, so that the latter can move forward when foot-operated 12 elongation；This Bring the furniture 1 for implementing this mechanism cushion elements must always behind portion have crack, gap 16 (in fig. 1 and 2 It can be seen that), and the crack, gap are inevitably related to its appearance and define relative building method.

When expectation, which is in, further includes extendible foot-operated 12 in the cushion elements of tool 1, the mechanism for being responsible for its movement is necessary The mechanism of movement with adjusting backrest 10 and headrest 11 couples, because riding 12 as it was previously stated, only extending, makes backrest 10 and head Pillow 11 is in its home position, will produce/the release position of taking one's seat of violation ergonomics, this will be ten over time Divide uncomfortable and unsustainable；According to the rule of ergonomics, the extension of the leg of user actually must be with use The back of person and the head of user are swayed, and therefore with by leaning on supporting that the coordination of organization of human body is on the move The inclination of the back of the body 10 and the rise of headrest 11, as shown in Figure 2.

In order to avoid the formation in gap 16, one might believe that --- only those mechanisms well known in the prior art can With --- either so that foot-operated 12 movement engages backrest 10 independently of the movement of backrest 10 or by seat 13.

However, these solutions cannot be realized reasonably, because the cushion elements of the furniture thus manufactured are not inconsistent not only The requirement of ergonomics is closed, and there is not pleasant appearance, and technically realizes to be also difficult and expensive.

In fact, if it is desired to realize the cushion elements of furniture, wherein foot-operated 12 extension and seat 13 travel forward Travelling forward for the rear portion 15 of backrest 10 will not be caused, to avoid rear gap 16 as shown in Figure 2 is produced, this will cause by The movement of deep crack 30 is produced between the back of the body 10 and headrest 11, as already explained, this deep crack will be so that take a seat/release position It is uncomfortable and aesthetically unacceptable (only for the purpose of clarification, as shown in Figure 3).

Another negative characteristics of above-mentioned legacy system are that existing mechanism always has large scale, as shown in Figure 4.
