Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a trim cover structure for a seat with a reclining device in which the seat back is attached to a seat cushion via a reclining device, and more particularly, a bag-like shape for covering the seat back. Related to the trim cover structure.

[Conventional technology]

For example, as a seat for a vehicle or the like, a seat occupant can tilt a seat back forward to adjust a tilt angle (reclining angle).
A seat with a reclining device provided between seat cushions is known.

Generally, in seat cushions and seat backs,
For example, a seat pad made of a urethane foam material or the like that gives a seated person sufficient elasticity is placed on a seat frame,
Alternatively, it is arranged around the seat frame. Then, such a seat pad is, for example, a trim cover in which at least two adjacent pieces of a front surface portion, a back surface portion, and a town portion of a separate body are connected via a bead or in a bag shape without a bead. A seat cushion and a seat back are formed so as to cover.

In such a seat with a reclining device formed from a seat cushion and a seat back, for example,
A configuration is known in which the mechanism portion of the reclining device is attached to the seat back side. In such a configuration,
The seat back is formed, for example, in a seat pad on the seat back side with a recess corresponding to the shape of the reclining device mechanism section, and the mechanism section is inserted into the recess on the seat back side through the gusset section of the trim cover. It is fitted and the reclining device is attached.

[Problems to be solved by the device]

However, since the trim cover of the seat back is formed in the shape of a bag, the gusset portion of the trim cover is in a pulled state even in the concave portion of the seat back side.
In other words, when the mechanical part of the liquid lining device is loosely fitted in the recess in such a state, the gusset part of the trim cover is pushed into the recess by the mechanical part and the trim cover is pulled by a distance corresponding to the depth of the recess. To be for that reason,
The pulled trim cover crushes the corners of the seat pad, forms a gap between the seat pad and the reclining device, and causes wrinkles in the trim cover to deteriorate the appearance quality of the seat back.

Further, by pulling the trim cover gusset portion by loosely fitting the mechanism portion of the reclining device into the recess, the rims in front of and behind the gusset portion are pulled inward. Therefore, meandering occurs at the bead, and in this respect as well, deterioration of the appearance quality cannot be avoided.

Then, while adjusting the tension of the trim cover, paying attention to the collapse of the seat pad and the occurrence of wrinkles on the skin,
Since the reclining device has to be attached, the work process becomes complicated and the workability deteriorates.

Here, a configuration is known in which, for example, a slit is provided at a position corresponding to the concave portion in the gusset portion of the trim cover so as to relieve tension in the gusset portion. In such a configuration,
By loosely fitting the mechanism portion of the reclining device in the seat back recess, the slit is widened and the tension of the trim cover gusset portion is relaxed. However, compared with the size of the mechanism part of the reclining device, the slit cannot be formed large, so the tension of the gusset is not sufficiently relaxed, and the seat pad is crushed due to the tension of the trim cover, and the beading of the bead, etc. Occurrence is unavoidable.

An object of the present invention is to provide a trim cover structure for a seat with a reclining device in which the reclining device can be attached to the side of the seat without deteriorating the appearance quality and workability of the seat.

[Means for Solving the Problems]

To achieve this object, according to the present invention, the gusset portion on the side surface of the trim cover is formed by being divided into a gusset body and a sub-cover, and at least one of the left and right ends of the sub-cover and the upper and lower ends thereof are formed. At least one of them is a free end.

Here, the sub-cover is arranged at a position that covers the recess of the seat pad.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, in a trim cover structure 10 for a seat with a reclining device according to the present invention, a trim cover 14 of a seat back 12 includes a gusset portion 16 forming a side surface and a gusset portion main body 18 and a sub portion. It is configured by being divided into a cover 20.

The seat back 12 of the seat 22 with the reclining device is formed by covering the seat pad 26 arranged around the seat frame 24 with the trim cover 14 as shown in FIG. 2, for example. The seat back trim cover 14
For example, a front surface portion 28, a back surface portion 30, which are separate bodies made of skin or the like,
At least two adjacent pieces of the pair of left and right gusset portions 16 (only one of which is shown in the figure) are joined together by sutures or the like via the bead edges 32 and 33 to form a bag shape. The bead 32, 33 is a bead cover made of a cord or the like, which is generally called a bead core 34, and made of a skin or the like.
Wrap with 36, the edge of the bead cover, for example, the surface portion 28,
It is interposed between the gusset portions 16 and integrally sewn. With such a configuration, the seam of the trim cover 14 is decorated by the bead edges 32 and 33, and the seam is prevented from being exposed. Therefore, it is possible to prevent the appearance quality of the seat back 12 from being deteriorated.

As shown in FIG. 2, the seat back 12 is swingably connected to a seat cushion 40, for example, via a pair of left and right reclining devices 38 arranged on both sides of the seat 22. The reclining device 38 is unitized in advance, for example, by projecting the mechanism portion 44 on the back surface of the arm plate 42, and the arm plate and the mechanism portion are integrally swingable with respect to the base plate 46. The reclining device 38 has a well-known configuration and is not the purpose of this invention, and therefore will not be described in detail.

And, for example, the seat pad 26 of the seat back is
The reclining device 38 is attached to the side of the seat 22 by being molded with a recess 48 on the side surface, and the mechanism portion 44 of the reclining device is loosely fitted in the recess via the gusset portion 16 of the trim cover.

Here, according to the trim cover mechanism 10 of the present invention, the first
As can be seen from FIGS. 2 and 3, the trim cover gusset portion 16 is divided into a gusset portion main body 18 and a sub-cover 20, and the sub-cover is arranged at a position to cover the recess 48 on the seat pad side. There is.

As shown in FIG. 1, the sub-cover 20 includes one of the left and right ends,
For example, the left end is connected to the front surface portion 28 of the trim cover via a bead 32 by stitching or the like, and one of the upper and lower ends, for example, the lower end is the front surface portion or the back surface portion of the trim cover.
It is connected to the lower end of 30 by means of sutures or the like via a bead. The right end and the upper end of the sub-cover 20 are free ends, and the right end is inserted between the back surface 30 of the trim cover and the seat pad 26, and the upper end is inserted between the gusset body 18 of the trim cover and the seat pad. The seat pad is held by the elasticity of the seat pad.

The left, right, top and bottom of the sub cover 20 refer to the top, bottom, left and right as viewed from the position facing the sub cover.

Here, if the terminal of the gusset body 18 of the trim cover is, for example, folded back inward and locked by stitching or the like, it is possible to prevent deterioration of the appearance quality due to the terminal of the gusset body.

In such a configuration, the reclining device 38 includes the mechanism portion 44 in the recess 48 on the seat back side and the sub-cover 20.
It is attached by loosely fitting through. Then, the mechanism portion 44 of the reclining device into the recess 48 of the seat pad.
With the loose fitting, the sub-cover 20 is pulled into the recess corresponding to the depth (thickness) of the mechanism portion. However, since the upper end and the right end of the sub-cover 20 are free ends and are merely inserted and sandwiched between the gusset main body 18, the back surface 30 and the seat pad 26 of the trim cover, respectively, the sub-cover is free. Only the upper end, which is the end, the right end is pulled, and the sub-cover corresponds to the recess 48.

That is, when the mechanism portion 44 of the reclining device is loosely fitted in the recess 48 of the seat pad, the upper end and the right end (free end) of the sub-cover function as a mechanism, regardless of the front surface portion 28, the rear surface portion 30, and the gusset body 18 of the trim cover. Since the seat pad 26 is pulled in accordance with the depth of the portion, the corners of the seat pad 26 are not crushed by the pulling of the trim cover 14. Therefore, there is no gap between the reclining device 38 and the trim cover 14, and the appearance quality does not deteriorate.

The left end and the lower end of the sub-cover 20 connected to the surface part 28 of the trim cover are the mechanical parts for the seat pad recess 48.
Since it is not pulled even when the 44 is loosely fitted, there is no meandering in the beads 32, 33.

Further, since the reclining device 38 is attached without paying attention to wrinkles caused by pulling the trim cover 14, the work process is simplified and the workability is improved.

Further, no slit is provided at the position corresponding to the seat pad recess 48 of the trim cover gusset portion 16 for relaxing the tension of the trim cover. Therefore, it is possible to reduce the number of working steps and sufficiently prevent wrinkles from occurring.

Here, in the trim cover structure 10 of the present invention, the upper end and the right end of the sub cover 20 are located between the trim cover rear surface portion 30 or the gusset body 18 and the seat pad 26, as can be seen from FIG. It is just inserted in each. However, the upper and right ends of the inserted sub cover 20 are
Back 30 of trim cover, town body 18 and seat pad
It is sandwiched between the seat and the seat 26 under the elasticity of the seat pad, and is held by the frictional forces of the trim cover and seat pad. Therefore, it is possible to prevent the back surface portion 30 of the trim cover and the upper end and the right end of the sub cover from being easily separated from the inside of the town portion main body 18.

Further, in the embodiment, the trim cover gusset body 18 is
The front surface portion 28 and the back surface portion 30 are respectively connected via the bead edges 32 and 33, but the present invention is not limited to this and may be directly connected without a bead edge. However, as in the example,
Trim cover front surface part 28 and rear surface part 30 via the bead edges 32 and 33.
With the configuration in which the trim cover is connected to the trim cover, the trim cover front surface portion and the back surface portion are stretched by the bead edges 32 and 33 respectively, so that the terminal is not bent and the appearance quality is not deteriorated.

Further, in the embodiment, the lower end and the left end of the sub-cover 20 are respectively connected to the trim cover surface portion 28, and the upper end and the right end are free ends. However, the present invention is not limited to this, and conversely, for example, the lower end and the left end of the sub-cover 20 are free ends, and the upper end is the town part 18 of the trim cover.
Alternatively, the right end may be connected to the back surface portion 30 by stitching or the like.

In the embodiment, the configuration in which the reclining device 38 is attached to the seat back side of the vehicle seat is illustrated and the trim cover structure 10 of the seat back 12 is described. However, it can also be applied as a trim cover structure in which the reclining device 38 is attached to the seat cushion side. In this case, the trim cover gusset portion of the seat cushion is divided into a gusset body and a sub-cover.

Further, although the trim cover structure of the present invention is suitable for a seat cushion and a seat back of a vehicle seat, the present invention is not limited to this, and can be applied to seats of trains, airplanes, ships and the like.

The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention in any way, and all modifications and alterations within the technical scope of the present invention are also included in the present invention. Needless to say.

[Effect of device]

As described above, according to the trim cover structure of the seat with the reclining device according to the present invention, the gusset portion on the side surface of the trim cover is divided into the gusset body and the sub-cover. And, at least one of the left and right ends of the sub-cover, and at least one of the upper and lower ends is a free end,
The sub cover is inserted and sandwiched between the adjacent trim cover and seat pad, and the sub cover is arranged at a position to cover the seat pad recess.

In other words, even if the mechanism portion of the reclining device is loosely fitted in the recess of the seat pad, only the free end of the sub-cover corresponds to the depth of the mechanism portion, regardless of the front surface portion, the rear surface portion, and the main body of the trim cover. Pulled.

Therefore, it is possible to prevent the corners of the seat pad from being crushed due to the pulling of the trim cover gusset and the meandering of the bead of the trim cover to be prevented, and the deterioration of the appearance quality of the seat can be prevented.

Further, since the reclining device can be easily attached without paying attention to wrinkles or the like generated in the gusset due to the pulling of the trim cover, the work process is simplified and the workability is improved.

Further, it is preferable that the free ends of the sub covers are inserted and sandwiched between the trim cover and the seat pad so as to overlap the ends of the adjacent trim covers. With such a configuration, the free end of the sub-cover is sufficiently held by the elasticity of the seat pad and the frictional forces of the trim cover and seat pad. for that reason,
It is possible to prevent the free end of the sub-cover from being easily separated from the space between the trim cover and the seat pad.
