Further, as shown in FIG. 5, a first projecting locking portion (2i) having a vertical projecting edge (2m) is formed at the front end portion of the rear end surface (2n), and is located above the rear end surface (2n) from the rear. Is formed with a triangular second protrusion locking portion (2h), and the second protrusion locking portion (2h) has a vertical protrusion edge (2l) and a 45 ° inclined protrusion edge (2p).
[0018]
As shown in FIG. 6, the side support (3) comprises a main body (31) and a hook-shaped attachment portion (32) attached to the base end of the main body (31), and the main body (31) has a loop shape. The peripheral frame portion (31a) and a cushioning support portion (31b) stretched on the inner side of the peripheral frame portion (31a). As shown in FIG. 7, projecting edges (32a, 32e) are formed on the front and rear sides of the inner surface of the bowl-shaped mounting portion (32), and the width W4 of the projecting edges (32a, 32e) The distance W2 between the guide surface (2d) of the side end surface and the first protruding locking portion (2h) is set to be the same, and the width W3 of the hook-shaped mounting portion (32) is the first protruding locking portion (2h). ) And the second protruding locking portion (2i) is set to be the same as the interval W1. The lower end portion of the hook-shaped attachment portion (32) protrudes downward from the main body (31), and a pivot attachment hole portion (32b) is provided at the center of the lower end portion, and the pivot attachment hole portion (32b ) Is provided with a projecting ring portion (32c).
[0019]
Explaining the mounting structure of the side support (3) to the base (2), as shown in FIGS. 3 and 8, the boss (2g) on the side surface of the base (2) is pivoted to the side support (3). The inner part of the projecting ring part (32c) of the part (32b) is fitted, and the projecting ring part (32c) of the inner periphery of the pivot hole (32b) is in contact with the front end surface of the boss (2g). Yes. An outer portion of the pivot hole (32b) that protrudes from the projecting ring portion (32c) is made of an elastic material such as rubber that biases the projecting ring portion (32c) toward the end surface of the base (2). The ring (33) is inserted, the tapping screw (35) is inserted through the washer (34), and the tapping screw (35) is screwed (tapped) into the screw insertion hole (2g) of the boss (2g). A cap (36) is fitted on the outside of the tapping screw (35) of the pivot hole (32b).
[0020]
To attach the side support member (1) to the seat (6), hold the side support member (1) by hand and the headrest is attached to the upper edge of the backrest (61) of the seat (6) from the front side of the seat (6). (5) and the backrest (61) are supported between the upper edge and a recessed notch (2b) provided at the rear edge of the base (2) of the side support member (1) is attached to the headrest (5 ) Abuts the stay (51) supporting the base (2) and pushes the base (2) backward. At this time, as shown in FIG. 9, the leaf spring body (2j) is pushed to the stay (51) via the locking projection (2k) and is bent toward the peripheral wall side of the recessed notch (2b). When the stay (51) is completely fitted into the concave notch (2b), the leaf spring body (2j) is elastically restored as shown in FIG. 10 to engage the leaf spring body (2j). The stop protrusion (2k) locks the stay (51) so as not to be disengaged from the stay fitting portion (2c) of the recessed notch (2b).
In this way, the base (2) of the side support member (1) is sandwiched between the upper edge of the backrest (61) and the headrest (5).
[0021]
To remove the side support member (1) from the seat (6), if the side support member (1) is held by hand and pulled forward, the stay (51) is locked to the locking projection (2k) as described above. The leaf spring body (2j) is pushed through the stay (51), and the stay (51) is pulled out from the stay fitting portion (2c) at the back end of the recessed notch (2b).
[0022]
In this way, the side support member (1) can be easily attached and detached between the seat (6) and the headrest (5), and after the attachment, the locking projection (2k) can be stably attached to the stay (51). Fixed.
[0023]
When the side support member (1) is in use, as shown in FIG. 11, the hook-like attachment portion (32) of the side support (3) is inserted into the pivot hole (32b) through the projecting ring portion (32c). The ring (33) is elastically pressed against the end surface side of the base (2), and both edges of the lower end portion of the hook-shaped attachment portion (32) are connected to the back end surface (2n) of the base (2) side portion. Are engaged with the projecting edges (2m, 2l) of the projecting latching portions (2h, 2i). At this time, the side support (3) attached to the hook-like attachment portion (32) is kept in the state of being pushed forward and pushed out as shown by the solid line in FIG. Therefore, the cushioning support part (31b) of the side support body (31) is positioned just in front of the headrest (5) and receives the head of the seated person.
[0024]
When storing the side support (3) without using the side support (3), hold the hook-shaped attachment part (32) of the side support (3) by hand and rotate it backward. At this time, the O-ring (33) in the pivot attachment hole (32b) is elastically deformed, and the projecting edge (32e) of the hook-shaped mounting part (32) resists the elasticity of the O-ring (33) to form the second protrusion Get over the protruding edge (2l) of the stop (2h). When the rear surface of the hook-shaped attachment portion (32) comes into contact with the guide surface (2d) at the end of the base (2), the O-ring (33) is restored, and the hook-shaped attachment portion (32) is Pressing against the end face side of the base (2) through the projecting ring part (32c), the projecting edge (32e) of the hook-shaped mounting part (32) is connected to the guide surface (2d) and the second projecting locking part (2h) And the hook-shaped attachment portion (32) is locked again.
At this time, as shown in FIG. 14, the hook-shaped mounting portion (32) is supported in a state inclined obliquely by 45 °, and the side support (3) attached to the hook-shaped mounting portion (32) is shown in FIG. As shown by the dotted line, it stands up almost vertically and does not disturb the seated person.
[0025]
In addition, in the case of a seated person such as a child who is short and has a low head, hold the hook-shaped attachment portion (32) of the side support (3) by hand and rotate it forward. At this time, since the O-ring (33) is elastically deformed as described above, the protruding edges (32a, 32e) of the hook-shaped mounting portion (32) get over the protruding edge (2m) of the first protruding locking portion (2i). Then, the front end of the side support (3) is brought into contact with the backrest (61) of the seat (6) as shown in FIG. In this way, the side support (3) is kept at a lower position than the headrest (5) as shown by the alternate long and short dash line in FIG. 14, and can accommodate a seated person such as a child whose head is in a low position.
[0026]
In the side support member (1) of this embodiment, a recessed notch (2b) for fitting the stay (51) of the headrest (5) is provided at the rear edge of the base (2). The recessed notch (2b) may be provided at the front edge of the base (2). In this case, to attach the side support member (1) to the seat (6), the backrest (61) of the seat (6) is placed between the headrest (5) attached to the upper edge and the upper edge of the seat (6). The base (2) of the side support member (1) is pushed into the rear side, and the stay (51) of the headrest (5) is fitted into the recessed notch (2b) of the base (2). The stay (51) is locked so as not to be detached from the recessed notch (2b) of the base (2).
[0027]
Further, the recess (2a) of the base (2) is not necessarily required.
The side support (3) may be attached to one end of the base (2), and the side support (3) is tilted forward from the state in which the side support (3) is raised to the side end surface of the base (2). There may be provided a locking projection that locks in multiple stages depending on the use state.
[0028]
【The invention's effect】
According to the side support member of the present invention, the side support member can be easily attached without removing the headrest from the seat, and it does not take time and effort.
