Description

Elastic support piece, elastic support assembly, chair back and chair

Technical Field

The invention relates to the field of seats, in particular to an elastic supporting piece, an elastic supporting assembly, a chair back and a chair.

Background

In the massage chairs known by those skilled in the art, the massage devices are all protruded from the elastic body of the chair back, and the user cannot use the massage chair as a common chair after the massage is finished, because the massage devices protruded from the elastic body can cause the user leaning against the chair back to be locally stressed, which results in fatigue or injury of the user. Particularly, in the field of vehicle driving seats, a driver is easy to fatigue when sitting on the driving seat for a long time, and the driving seat has the objective requirement of massage, but meanwhile, in a normal driving state, the massager protrudes out of the elastic body, and the driver is easy to be injured due to acceleration when driving at a high speed.

To solve this problem, those skilled in the art have tried to construct a retractable massager which protrudes from the back of the chair during massage and is controlled to retract into the elastic body when used as a general chair. To achieve this, a channel is created for the massager to telescope.

Disclosure of Invention

It is an object of the present invention to overcome the above-mentioned drawbacks or problems of the background art and to provide a resilient support, a resilient support assembly, a chair back and a chair that can establish a passageway for a massager to extend and retract to help resolve the problem of switching between a massage mode and a non-massage mode of a massage chair. In particular, it ensures both reliable extension and retraction of the massager during long-term use, and deformation following compression of the elastic body of the chair back when the massager is retracted, so as to avoid fatigue of the user due to local stress.

In order to achieve the purpose, the following technical scheme is adopted:

a resilient support member, comprising: the channel piece comprises a bottom support, a sheath and a pipe body for connecting the bottom support and the sheath, the pipe body is provided with a channel along the extending direction of the pipe body, at least part of the pipe body is a folding deformation part which is allowed to stretch along the extending direction of the pipe body, and the outer wall of the folding deformation part forms a folding groove; the elastic body is formed outside the channel piece in a foaming mode and embedded into the folding groove, and is provided with a first surface and a second surface, wherein the first surface is flush with the end face of the sheath, and the second surface is far away from the first surface.

Further, the folding deformation part is a corrugated hose or a spiral hose.

Further, the sheath is provided with a first hole communicating with the passage.

Further, the bottom support is provided with a second hole communicated with the channel.

Further, the end surface of the shoe facing away from the sheath is flush, convex or concave relative to the second surface.

Further, the part of the pipe body close to the sheath is a straight pipe part connected with the folding deformation part.

A resilient support assembly comprising a base and a resilient support as described in any preceding claim, the base supporting the second surface of the resilient body and being removably secured to the shoe.

A chair back comprises a cladding piece and the elastic supporting component, wherein the cladding piece wraps the elastic supporting piece and is fixedly connected with the base body.

A chair comprising a seat and a back as described above, said base being attached to said seat.

Compared with the prior art, the scheme has the following beneficial effects:

in the invention, the sheath of the channel piece is connected with the first surface of the elastic body for supporting, and at least part of the pipe body is the folding deformation part, so that the channel piece can stretch along with the stretching of the elastic body, and the fatigue of a user caused by local stress is avoided. However, when the channel member expands and contracts along with the expansion and contraction of the elastic body, it cannot be guaranteed that the folding deformation portion does not flex. And the bending of the folding deformation part can cause the massager to be incapable of reliably stretching. Therefore, in the above technical solution, the elastic body is further limited to be embedded in the folding groove. Because the elastic body is embedded into the folding groove, the folding deformation part can be supported in the radial direction (perpendicular to the extending direction of the tube body), so that the folding deformation part is not easy to flex, and can be restored along with the elastic body when the human body leaves the chair back when the folding deformation part is flexed to a certain extent, thereby being beneficial to providing a telescopic channel for the massager reliably in long-term use.

In the invention, the end face of the sheath, which is far away from the bottom support, is flush with the first surface, so that the sheath does not press against the human body when the human body abuts against the elastic body, and the fatigue or damage of the human body caused by local stress is further avoided.

Because the sheath is provided with the first hole communicated with the channel, the massager can protrude out of the sheath, namely can protrude out of the first surface.

In the invention, the bottom support is provided with the second hole communicated with the channel, so that the air pressure balance can be kept when the massager stretches in the channel, the massager can stretch smoothly, and the channel has the functions of ventilation, heat exchange and the like.

In the invention, the end surface of the bottom support departing from the sheath is flush, convex or concave relative to the second surface, so the length of the channel can be adjusted according to the telescopic stroke of the massager. When the length of the channel needs to be longer, the end face of the bottom support protrudes out of the second surface, and when the length of the channel needs to be shorter, the end face of the bottom support is recessed into the second surface.

In the invention, the part of the pipe body close to the sheath is the straight pipe part connected with the folding deformation part, so that radial rigid support can be provided for the massager at the vibration part of the massager.

In the invention, the bottom support is detachably and fixedly connected with the base body, so that the bottom support can be used for supporting the base body, when the elastic body deforms, the position of the bottom support is always kept, and the deformation of the channel piece always comes from the expansion of the folding deformation part.

Referring to fig. 2, fig. 2 shows the elastic support 1 in an embodiment. As shown in fig. 2, the elastic support member 1 includes two channel members 2 and an elastic body 10.

Referring to fig. 1 and 3, as shown in fig. 3, the number of the passage members 2 is two in the present embodiment, and in other embodiments, the number of the passage members 2 may be one or more than two. Each channel element 2 comprises a shoe 3, a sheath 4 and a tubular body 6 connecting the shoe 3 and the sheath 4. In this embodiment, the bottom supports 3 of the two channel members 2 are both thin plates and are connected into a whole. The shoe 3 of each channel member 2 is provided with at least one second aperture 13. In this embodiment, the two sheaths 4 are both in the shape of a thin sheet, and as shown in fig. 3, a first hole 5 is formed in the center of each sheath 4. Body 6 connects collet 3 and sheath 4, and body 6 can be as an organic whole with collet 3 and sheath 4 even, also can connect collet 3 and sheath 4 through the mode of rigid coupling. The tubular body 6 is provided with a passage 9 along its extension, communicating both with the first hole 5 and with the second hole 13. The part of the pipe body 6 close to the bottom support 3 is a folding deformation part 7, the outer wall of the folding deformation part 7 forms a folding groove, and the part of the pipe body 6 close to the sheath 4 is a straight pipe part 8 jointed with the folding deformation part 7. Wherein, the folding deformation part 7 is a corrugated pipe or a spiral hose.

Referring to fig. 2, the resilient body 10 is formed by foaming out of each channel member 2, as shown in fig. 2, so that the resilient body 10 is embedded in the folded recess of the fold-forming part 7 and is provided with a first surface 11 which is flush with the end surface of the sheath 4 facing away from the shoe 3 and a second surface 12 facing away from the first surface 11. Wherein the first surface 11 is used to provide support and the second surface 12 is used to be supported by other objects. In this embodiment, the end surface of the shoe 3 facing away from the sheath 4 is flush with the second surface 12. In this embodiment, as shown in fig. 5 and 6, the end surface of the shoe 3 facing away from the sheath 4 may also be convex or concave with respect to the second plane.

Referring to fig. 4, as shown in fig. 4, the elastic support assembly 14 in the present embodiment includes the elastic support member 1 in the present embodiment and a base 15. The base 15 is generally a relatively rigid member, for example, the base 15 may be a back plate, or may include a frame and a steel wire mesh suspended from the frame. Which provides support for the spring, and in particular, the base 15 is used to support the second surface 12 of the spring 10. The base body 15 is detachably fastened to the base support 3, for example, by screwing.

The present embodiment also provides a chair back, as shown in fig. 1, which includes a cover and the flexible support assembly 14 of the present embodiment. The covering member is generally made of leather or leather, and covers the elastic supporting member 1 and is fixedly connected with the base 15. The manner of the covering member including the elastic supporting member 1 and the manner of fixedly connecting the covering member to the base 15 are the prior art, and are not described herein again.

This embodiment also provides a chair (not shown) comprising a seat and the back of the chair of this embodiment. Wherein, base member 15 connects in the seat support, and specifically, base member 15 can rigid coupling in the seat support, also can rotate to connect in the seat support, and its specific connected mode is prior art, and no longer repeated here.

Fig. 7 and 8 show the manner of use of the present embodiment. As shown in fig. 7, when the chair is in the massage state, the massager 16 extends out of the channel 9 and protrudes out of the first surface 11, and massages the back of the human body by rotating and/or vibrating. As shown in figure 8, the massager 16 is retracted into the channel 9 and buried below the first surface 11 when the chair is in a non-massaging state. At this time, the user can use the chair as a seat normally. When the user backs on the back of the chair, the pressure of the back causes the elastic body 10 to compress, while also causing the fold deformations 7 to compress through the sheath 4. At this time, the massager 16 is not protruded out of the first surface 11, so that the user is not fatigued or damaged due to local stress. Moreover, since the elastic body 10 is embedded in the folding groove of the folding deformation part 7, not only can the folding deformation part 7 be supported in the radial direction (perpendicular to the extending direction of the tube body 6) so as to be not easy to bend, but also the folding deformation part 7 can be restored along with the elastic body 10 when the human body leaves the back of the chair even if a certain bending occurs, which is beneficial to reliably providing the telescopic channel 9 for the massager 16 in long-term use. Meanwhile, the end face of the sheath 4 departing from the bottom support 3 is flush with the first surface 11, so that when a human body leans against the elastic body 10, the sheath 4 does not press against the human body, and fatigue or damage of the human body caused by local stress is further avoided. In this embodiment, since the sheath 4 is provided with the first hole 5 communicating with the passage 9, the massager 16 can protrude from the sheath 4, that is, from the first surface 11. Because the bottom support 3 is provided with the second hole 13 communicated with the channel 9, the air pressure balance can be kept when the massager 16 stretches in the channel 9, the massager 16 can stretch smoothly, and the channel 9 can have functions of ventilation, heat exchange and the like. In this embodiment, since the portion of the tube body 6 close to the sheath 4 is the straight tube portion 8 connected to the folded deformation portion 7, a radial rigid support can be provided for the massager 16 at the vibration portion of the massager 16. In this embodiment, the bottom support 3 of the two channel members 2 is connected to form a single body, so that the bottom support 3 can have better support. And collet 3 detachably and base member 15 rigid coupling, so collet 3 can mention the support of base member 15, and when making elastomer 10 deformation, collet 3's position remains throughout, and makes the deformation of passageway piece 2 derive from folding the flexible of deformation portion 7 throughout.

In other embodiments, the length of the channel 9 can be adjusted according to the telescopic stroke of the massager 16, since the end surface of the shoe 3 facing away from the sheath 4 can be arranged to be convex or concave relative to the second surface 12. When channel 9 needs to be longer, the end surface of shoe 3 protrudes from second surface 12, and when channel 9 needs to be shorter, the end surface of shoe 3 is recessed from second surface 12. The structural design is facilitated according to the actual situation.

The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting.
