Description

  The present invention relates to a seat having a seat back having a function as an assist grip that can be used when an occupant gets on and off.

  Conventionally, as a technique in such a field, there is Japanese Utility Model Publication No. 4-35933. The resin-made assist grip provided in the seat described in this publication includes a main body portion disposed between the lower surface of the headrest and the top surface of the seat back, and a pair of holding cylinder portions depending downward from the main body portion. And a grip portion protruding rearward from the back surface of the main body portion. The holding cylinder part is inserted into a cylinder part fixed to the upper part of the seat back frame, and has a stay insertion hole for inserting a stay extended from the headrest. Such an assist grip can achieve both a grip function that can be used when passengers get on and off and a function that holds the stay of the headrest.

There is Japanese Utility Model Publication No. 4-35933.

  However, the grip portion of the assist grip provided in the conventional seat described above needs to protrude from the back of the seat back in order to be used when the passenger gets on and off, and between the front seat and the rear seat. There is a problem that it becomes an obstacle to movement.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a seat that has an assist grip that does not obstruct movement between the front seat and the rear seat and a pocket function for storing objects.

The present invention, in a seat provided with a headrest on the seat back,
The concave portion of the fingertip insert in the form of a molded body made of a soft material that can be connected by stitching is embedded in the top of the seat back,
The seat back is provided with a pair of left and right cylindrical headrest supports that support a stay extending from the headrest, and the headrest supports are attached to an upper frame that extends laterally within the seatback. Fixed,
A flange-like connecting portion is integrally formed on the periphery of the opening of the concave portion in the fingertip insert, and the periphery of the opening of the connecting portion is sewn to the periphery of the mounting hole of the trim cover of the seat back. In addition, an extension piece having an insertion hole through which the left and right headrest support bodies can be inserted is integrally extended from the concave portion of the fingertip insert body separately from the connection portion, and is formed in the extension piece. The movement of the fingertip insert relative to the headrest support can be restricted by inserting the left and right headrest supports into the paired left and right insertion holes, respectively.

In this seat, since the concave portion of the container-like fingertip insert is embedded in the top of the seat back, the grip function does not protrude from the back of the seat back, and when the passenger gets on and off, The movement between the rear seats can be performed smoothly, and the concave portion can function as a pocket.
In addition, since the fingertip inserts sewn on the trim cover are formed of a soft material, the fingertip inserts are easily deformed by the force of the fingertips of the occupant's hands, and the surrounding trim cover is pulled by the deformation of the fingertip inserts. Further, appearance defects such as wrinkles occur, and the deformation of the concave portion of the fingertip insert due to the force of the occupant's fingertips also leads to insufficient rigidity of the grip function. However, the periphery of the opening of the concave portion in the connecting portion of the fingertip insert is sewn to the periphery of the mounting hole of the seat cover trim cover, and the left and right headrest supports are attached to the insertion holes formed in the extension piece. By inserting each, the movement of the fingertip insert relative to the headrest support for supporting the stay can be restricted. In this way, by cooperating with the insertion hole of the extension piece and the pair of right and left headrest supports, both the sewing performance to the trim cover and the stability of the grip function can be achieved while taking advantage of the material characteristics of the fingertip insert. Can do.
In addition, since the extension piece is integrally extended from the concave portion of the fingertip insert separately from the connection portion, the extension piece becomes an obstacle when the connection portion of the fingertip insert is sewn to the trim cover with a sewing machine. Therefore, the workability of sewing can be improved.
Furthermore, since the fingertip insert is molded into a container shape from a soft material and embedded in the top of the seat back, it can be a cushioning material that protects the head of the passenger in the rear seat at the time of a rear-end collision of an automobile. .

  Further, it is preferable that the connecting portion is provided so as to be shifted from the opening edge of the fingertip insertion body toward the bottom of the concave portion by the thickness of the sewing end of the trim cover.

  By such stitching, the stitched portion of the trim cover with respect to the fingertip insert is not turned up, so that the appearance quality of the trim cover can be improved. And integration of a fingertip insert and a seat back can be achieved easily and reliably.

  Further, it is preferable that the concave portion of the fingertip insert is disposed adjacent to the front side of the upper frame between the left and right headrest supports.

  If such a structure is employ | adopted, the movement to the left and right and back of the recessed part of a fingertip insertion body can be controlled easily and simply by the left and right headrest support bodies and the upper frame.

  According to the seat according to the present invention, it is possible to combine the realization of an assist grip that does not hinder the movement between the front seat and the rear seat and the pocket function for inserting an object.

As shown in FIGS. 1 to 4, the seat includes a seat back SB that can tilt with respect to the seat cushion SC, and a headrest HR is disposed above the seat back SB.

  The headrest HR may have a conventionally well-known structure. For example, when the trim cover 3 formed in a predetermined shape by a press in a state in which a synthetic resin is coated on a nonwoven fabric is used, shape retention is obtained. The headrest HR is formed on the trim cover 3, the pad body 2 formed by curing the foaming liquid injected into the trim cover 3, and the headrest frame 1 fixed in the pad body 2. The stay 1 a extends from the cover 3.

  The seat back SB may have a conventionally well-known structure, but the illustrated seat back SB is formed into a predetermined shape by a press in a state in which, for example, a synthetic resin is coated on a non-woven fabric, thereby improving shape retention. A trim cover 11 that is covered, a pad body 10 that is loaded into the trim cover 11, a seat back frame 2 that is formed by bending a pipe in an inverted U-shape that is fixed in the pad body 10, and the seat back frame 2 A pair of left and right cylinders 5 fixed to the upper frame 2a extending in the lateral direction at the upper end by welding and extending in the vertical direction to support the stay 1a with the upper frame 2a, and in each cylinder 5 A resin-made cylindrical headless member that is inserted and locked and has a head portion 6a formed at the upper end so that the stay 1a can be inserted from above. The support 6 is composed mainly of.

  The pad body 10 is formed integrally with the foamed liquid injected into the trim cover 11, and the pad body 10 is formed separately from the trim cover 11 and inserted into the trim cover 11. There is. In the present invention, both types of applications are possible.

  In addition, an insertion hole that allows the cylindrical headrest support 6 to be inserted is formed at the top of the trim cover 11, and an insertion hole that allows the headrest support 6 to be inserted also at the top of the pad body 10. Is formed. In order to enable insertion of the headrest support 6, the insertion hole on the trim cover 11 side and the insertion hole on the pad body 10 side are aligned.

  A recessed portion 50b provided in a molded-container-shaped fingertip insertion body 50 that allows insertion of fingertips of the passenger's hand is embedded in the top portion of the seat back SB. The concave portion 50b of the fingertip insert 50 is formed with a flange-like connecting portion 50a extending from the peripheral edge of the opening 50c of the fingertip insert 50. The fingertip insert 50 having such a configuration is formed into a container shape from a soft material that can be connected to the trim cover 11 by stitching, for example, a soft synthetic resin such as an elastomer.

  At the top of the trim cover 11, a mounting hole that allows the insertion of the concave portion 50 b of the fingertip insertion body 50 is formed, and this mounting hole is disposed behind the insertion hole at the top of the trim cover 11. An insertion hole that allows insertion of the concave portion 50b of the fingertip insertion body 50 is also formed at the top of the pad body 10, and this insertion hole is arranged behind the insertion hole at the top of the pad body 10. And in order to make mounting | wearing of the recessed part 20b possible, position alignment with the attachment hole by the side of the trim cover 11 and the insertion hole by the side of the pad body 10 is made.

  At the periphery of the opening 20c of the fingertip insert 50, the connecting portion 50a of the fingertip insert 50 is sewn by the stitching portion R at the periphery of the mounting hole provided in the top of the trim cover 11, so that the trim cover 11. The connecting portion 50a is provided so as to be shifted from the upper end edge 50d of the opening 50c of the fingertip insert 50 toward the bottom of the concave portion 50b by the thickness of the stitched end turned back to form the attachment hole of the trim cover 11. It has been. By such stitching, the peripheral edge of the mounting hole of the trim cover 11 is not turned up, so that the appearance quality of the peripheral edge of the mounting hole of the trim cover 11 can be improved. And integration of the fingertip insert 20 and the seat back SB can be achieved easily and reliably.

  Since the fingertip insert 50 sewn to the trim cover 11 is formed of a soft material, the fingertip insert 50 is easily deformed by the fingertip force of the occupant's hand. 11 is pulled, the insertion hole is exposed around the head portion 6a of the headrest support 6, and appearance defects such as wrinkles are liable to occur. Furthermore, the concave portion 20b of the fingertip insert 20 due to the fingertip force. This deformation also leads to insufficient grip function rigidity.

  However, in order to achieve both the sewing property to the trim cover 11 and the stability of the grip function while taking advantage of the material characteristics of the fingertip insert 50, as shown in FIG. In the lower concave portion 50b, a pair of left and right extending pieces 51, 51 having insertion holes 51a, 51a through which the left and right headrest support bodies 6 can be inserted are provided separately from the connecting portion 50a.

By inserting the left and right headrest supports 6 into the through holes 51a, 51a, respectively. The lateral movement of the fingertip insert 50 with respect to the headrest support 6 is restricted.

  Therefore, even if the fingertip insert 50 to be sewn on the trim cover 11 is formed of a soft material, both the sewing performance to the trim cover 11 and the stability of the grip function can be achieved. Moreover, the assembly workability is improved by providing each insertion hole 50d in the fingertip insert 50.

  Further, when the fingertip insert 5 is sewn to the trim cover 11 with a sewing machine, the extending pieces 51 and 51 can be bent so as not to get in the way, so that the sewing workability is improved.

  The headrest HR located above the fingertip insert 50 is formed with a notch 4 for exposing the opening 20c of the fingertip insert 50. The notch 4 has a substantially concave shape in cross section that is the back surface 8a of the headrest HR and has an open bottom surface. With such a configuration, the opening 50c of the fingertip insert 50 can be easily exposed without impairing the cushioning properties of the headrest HR. The notch 4 is wider than the lateral width of the fingertip insert 50 on the back side of the headrest HR, and becomes wider toward the lower side, so that the opening of the fingertip insert 50 is secured while ensuring a sufficient width. It becomes easy to insert a fingertip into the portion 50c from above.
