Description

図１、図２に示すように、この発明に係るシートバックのトリムカバー吊り込み構造10においては、スリット、たとえば壁付きスリット12の設けられた係止プレート14が、シートバックフレーム16の左右サイド間での架設、固定によってシートバック本体18に配設されるとともに、この係止プレートの壁付きスリットに挿入、係止可能なフックプレート20が、シートバック本体の周面を被覆するトリムカバー22の背裏の内面に固着されている。 As shown in Figures 1 and 2, in the seat back trim cover hanging structure 10 of this invention, a locking plate 14 having a slit, for example, a walled slit 12, is disposed on a seat back main body 18 by being stretched and fixed between the left and right sides of a seat back frame 16, and a hook plate 20 that can be inserted into and locked into the walled slit of this locking plate is fixed to the inner surface of the back of a trim cover 22 that covers the peripheral surface of the seat back main body.

上記のように、この発明のシートバックのトリムカバー吊り込み構造10においては、フックプレート20を、略袋状のトリムカバー22の背裏外方から、係止プレートの壁付きスリット12（スリット）に挿入、係止すれば足りるため、トリムカバーの吊り込み作業の際における、トリムカバー内での手探り作業が不要となる。 As described above, in the seat back trim cover hanging structure 10 of this invention, it is sufficient to insert and lock the hook plate 20 into the walled slit 12 (slit) of the locking plate from the outside of the back of the approximately bag-shaped trim cover 22, so there is no need to feel around inside the trim cover when hanging the trim cover.

【発明の効果】
上記のように、この発明に係るシートバックのトリムカバー吊り込み構造によれば、フックプレートを、略袋状のトリムカバーの背裏外方から、係止プレートのスリット、具体的には壁付きスリットに挿入、係止すれば足りるため、トリムカバーの吊り込み作業の際における、トリムカバー内での手探り作業が不要となる。 [0048]
[Effects of the Invention]
As described above, according to the seat back trim cover hanging structure of the present invention, it is sufficient to insert and lock the hook plate into the slit in the locking plate, specifically the walled slit, from the outside of the back of the approximately bag-shaped trim cover, so there is no need to feel around inside the trim cover when hanging it.

そして、底面を有する略逆台形状凹部、あるいはスリットの下方をフックプレートの押し込み方向前方に窪ませた略逆三角形状凹部を、凹部として係止プレートに設ければ、壁付きスリット（スリット）の位置の明確化がはかられるばかりでなく、凹部によって、係止プレートが補強されるため、構成の複雑化を伴うことなく、係止プレートの変形等の防止がはかられる。 Furthermore, if a recess having an approximately inverted trapezoidal shape with a bottom surface, or an approximately inverted triangular shape with the lower part of the slit recessed forward in the direction of pushing the hook plate , is provided in the locking plate as a recess, not only will the position of the walled slit (slit) be clarified, but the recess will also reinforce the locking plate, thereby preventing deformation of the locking plate without complicating the configuration.

Claims

The seat back is a seat back body formed by disposing a seat pad around a seat back frame, and the peripheral surface of the seat back body is covered with a substantially bag-shaped trim cover, and a predetermined part of the back of the seat back is partially suspended and engaged with the seat back body.
A locking plate having at least upper and lower peripheral walls erected in the front direction of the seat back body and provided with a walled slit extending in the left-right direction is installed and fixed between the left and right sides of the seat back frame so that at least the opening of the walled slit can be aligned and exposed at a hanging position on the back of the seat back body,
A hook plate having integral hook pieces that can be inserted into the walled slit from the opening under forcible and elastic contraction caused by external pressure and that irremovably engage with the end of at least one of the upper and lower peripheral walls of the walled slit by restoring its shape after insertion is fixed to the inner surface of the back of the trim cover at a position that can be aligned with the walled slit,
A seat back trim cover hanging structure characterized in that a step of a height that allows the hook piece to engage and serves as a guide when inserting the hook plate into the walled slit is provided between the upper and lower ends of the opening of the walled slit.

The seat back is an adhesively molded seat back in which the peripheral surface of the seat back body, which is formed by disposing a seat pad around a seat back frame, is covered with a substantially bag-shaped trim cover which is attached to the seating surface side, and a predetermined portion of the back of the trim cover is partially hung and engaged with the seat back body,
A locking plate having at least upper and lower peripheral walls erected in the front direction of the seat back body and provided with a walled slit extending in the left-right direction is installed and fixed between the left and right sides of the seat back frame so that at least the opening of the walled slit can be aligned and exposed at a hanging position on the back of the seat back body,
A hook plate having integral hook pieces that can be inserted into the walled slit from the opening under forcible and elastic contraction caused by external pressure and that irremovably engage with the end of at least one of the upper and lower peripheral walls of the walled slit by restoring its shape after insertion is fixed to the inner surface of the back of the trim cover at a position that can be aligned with the walled slit,
A seat back trim cover hanging structure characterized in that a step of a height that allows the hook piece to engage and serves as a guide when inserting the hook plate into the walled slit is provided between the upper and lower ends of the opening of the walled slit.

3. A seat back trim cover hanging structure according to claim 1 or 2, wherein the locking plate is formed with a recess on the rear side of the seat back body that extends in the left-right direction and has a generally inverted trapezoidal cross section, and the walled slit is provided at the bottom of this recess, continuing to either the side surface located above or below the bottom, thereby forming a step between the upper and lower ends of the opening of the walled slit.

3. The seat back trim cover hanging structure according to claim 1 or 2, wherein the locking plate has a recess on the rear side of the seat back body that extends in the left-right direction and has a generally inverted triangular shape in longitudinal section, and the walled slit is provided at the apex of this recess, continuing on either the upper or lower side, thereby forming a step between the upper and lower ends of the opening of the walled slit.

A seat back trim cover hanging structure according to any one of claims 1 to 4, wherein the lower part of the walled slit is aligned and exposed at the hanging position on the back of the seat back body, the locking plate is arranged on the seat back body, and the lower end of the opening of the walled slit is positioned closer to the front side of the seat back body than its upper end.

6. A seat back trim cover hanging structure as claimed in any one of claims 1 to 5, wherein the hook plate is molded from a synthetic resin material into a generally J-shaped side surface having a hook piece at one end that is elastically deformable in the widthwise direction under the action of external pressure.

In a seat back in which the peripheral surface of a seat back body formed by disposing a seat pad around a seat back frame is covered with a substantially bag-shaped trim cover, and a predetermined portion of the back of the seat back is partially suspended and engaged with the seat back body,
A hook plate having a hook piece integrally formed therewith is fixed to the inner surface of the back of the trim cover, and a locking plate fixed to the seat back frame is provided with a slit into which the hook piece of the hook plate can be inserted and engaged;
The seat back trim cover hanging structure is characterized in that the hook pieces of the hook plate are engaged with each other by pushing them into the slits against the elastic force of the seat pad.

8. The seat back trim cover hanging structure according to claim 7, wherein a portion below the slit provided in the locking plate is recessed forward in the pushing direction of the hook plate.
