Utility model registration No. 3066067

The holder can only be used in a fixed position. For this reason, there is a concern that the holder can only be placed in a position that is difficult for the seated person to use or a position that interferes with sitting, which is inconvenient. Therefore, the present invention provides a vehicle seat equipped with a holder that is more convenient.

In order to solve the above problems, the vehicle seat of the present invention takes the following measures.

That is, the vehicle seat of the present invention includes a seat back, a table that is rotatably assembled around the rotation axis, and a rotation axis that is provided to extend in the width direction of the seat along the back surface of the seat back. On the other hand, it has a holder that is slidable in the seat width direction along the rotation axis and/or assembled to be rotatable about the rotation axis.

According to the above configuration, the holder can be slid in the seat width direction and/or rotated about the rotation axis, so that the position of the holder can be changed. Thereby, the holder can be placed in any position or orientation convenient for the seated person, and convenience can be improved. Furthermore, by providing the holder using the rotating shaft, there is no need to separately provide a configuration for assembling the holder to the back surface of the seat back. Therefore, the holder can be rationally assembled to the seat back.

Furthermore, the vehicle seat of the present invention may be further configured as follows. The rotating shaft spans between the tips of a pair of left and right arms that extend rearward from the back of the seat back and are rotatable relative to the seat back about the same axis as the center axis of reclining the seat back. It is attached. According to the above configuration, the rotating shaft is provided so as to extend in the seat width direction at a position that extends further rearward from the back surface of the seat back. Thereby, the holder can be placed closer to the seated person.

Furthermore, the vehicle seat of the present invention may be further configured as follows. The holder is removably stored in a concave storage portion formed on the back surface of the table by rotation about a rotation axis. According to the above configuration, the holder can be stored on the back surface of the table when not in use. Thereby, the holder is less likely to get in the way of the seated person, and convenience can be further improved.

Furthermore, the vehicle seat of the present invention may be further configured as follows. The table can be switched between a deployed position where the table is deployed horizontally, and a stored position where the table is folded in an overlapping manner on the back of the seat back by rotation and raised upward from the deployed position. A holder is located on the back side of the table. According to the above configuration, the holder can be used even when the table is in the storage position. Furthermore, the table can be unfolded even when the holder is used, and the holder does not obstruct the usable surface (surface) space of the table.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A mode for carrying out the present invention will be described below with reference to FIGS. 1-11. In the following description, when directions such as front, back, top, bottom, left, and right are indicated, the respective directions shown in each figure are referred to. In addition, when referring to "the sheet width direction", it refers to the left-right direction of the sheet 1, which will be described later.

<First embodiment>
First, a sheet 1 according to a first embodiment of the present invention will be described. Seat 1 is a seat used in an aircraft. As shown in FIG. 1, the seat 1 includes a seat back 2 that serves as a backrest for a seated person, and a seat cushion (not shown) that serves as a seating portion. The seat 1 also includes a table 3 provided on the back surface of the seat back 2, and a bottle holder 10 that hooks and holds the neck of a plastic bottle 7 at the bottom of the table 3.

The table 3 is supported by a rotating shaft 5 that spans between the tips of a pair of left and right arms 4 extending from the bottom of the seat 1. The rotation shaft 5 is provided so as to extend in the seat width direction along the back surface of the seat back 2. The table 3 is rotatably assembled to the rotating shaft 5. As a result, a person sitting in the rear seat of seat 1 can fold and store the table 3 so that it overlaps the back of the seat back 2 (storage position), or unfold it horizontally and use it, as shown in Figure 2. (deployed position).

<Table 3>
Each structure of the sheet 1 will be described in detail below. The table 3 is a substantially rectangular member formed along the width of the back surface of the seat back 2, as shown in FIG. The table 3 has a concave cutout at the center of the upper end in the storage position. The table 3 in the storage position is supported at its lower end by the rotating shaft 5 so as to rotate about the rotating shaft 5 as a lower hinge. Further, the table 3 in the storage position is supported at its upper end central portion from behind by a stopper 3c provided on the back surface of the seat back 2. As a result, the table 3 is prevented from rotating backward about the rotating shaft 5 and is held at the storage position. When the support by the stopper 3c is released, the table 3 rotates backward around the rotating shaft 5 due to the action of gravity and is unfolded horizontally, as shown in FIG. Further, at the same time as the table 3 rotates, an arm 4, which will be described later, rotates backward to a predetermined position.

As shown in FIGS. 4 and 5, the table 3 has a rectangular recessed storage section 3a on its back surface. As shown in FIGS. 3, 6, and 7, a holder portion 11 of a bottle holder 10, which will be described later, can be fitted and held in the storage portion 3a. Therefore, the storage section 3a is formed in a shape that follows the shape of the holder section 11. As shown in FIG. 5, the table 3 has convex locking claws 3b projecting from each inner side surface of the storage section 3a in the seat width direction. The holder part 11 is held in a fitted state in the storage part 3a by each of the locking claws 3b sandwiching and supporting the holder part 11.

<Arm 4>
As shown in FIG. 2, each arm 4 is rotatably assembled to a reclining center shaft 6 of the seat back 2. Thereby, each arm 4 can rotate following the reclining of the seat back 2 in the retracted state in which the table 3 is engaged with the seat back 2 by the stopper 3c. Furthermore, when the table 3 is disengaged from the seat back 2 and expanded, each arm 4 does not follow the reclining motion of the seat back 2, but can release the reclining motion of the seat back 2.

As shown in FIG. 6, the tip of each arm 4 extends rearward from the back surface of the seat back 2 even when the table 3 is in the retracted position. The rotating shaft 5 is provided in a bridging manner between the tips of each arm 4. As a result, the rotating shaft 5 is located behind the back surface of the seat back 2 and extends in the seat width direction at a position closer to the rear seat occupant. Therefore, the bottle holder 10 attached to the rotating shaft 5 can be provided at a position closer to the seated person.

<Bottle holder 10>
As shown in FIG. 5, the bottle holder 10 includes a holder part 11 on which the neck of the plastic bottle 7 is hooked, and a leather band 12 that connects the holder part 11 and the rotating shaft 5. The bottle holder 10 is provided so as to be suspended downward from the rotating shaft 5. The bottle holder 10 is located on the back side of the table 3. Here, the bottle holder 10 corresponds to the "holder" of the present invention.

As shown in FIG. 5, the holder portion 11 has a circular through hole 11a and a fitting hole 11b which is elongated and communicates with the through hole 11a. The through hole 11a is formed in a size that allows the lid of the plastic bottle 7 to be inserted therethrough. The fitting hole 11b is formed to be larger than the neck of the plastic bottle 7 and smaller than the lid of the plastic bottle 7. As shown in FIG. 1, the holder part 11 is in a state in which the PET bottle 7 is hooked by inserting the lid of the PET bottle 7 into the through hole 11a and then sliding the neck of the PET bottle 7 into the fitting hole 11b. It is possible to hold the

Further, as shown in FIGS. 5 and 7, the holder portion 11 has a chamfered portion 11d at the peripheral edge of the fitting hole 11b. Specifically, as shown in FIG. 7, the chamfered portion 11d is formed at the peripheral edge of the fitting hole 11b on the side facing the housing portion 3a in the holder portion 11 housed in the housing portion 3a. A gap is formed between the storage section 3a and the holder section 11 by the chamfered section 11d. Thereby, a person sitting in the rear seat can easily pull out the holder part 11 stored in the storage part 3a by hooking his or her finger on the chamfered part 11d.

Further, as shown in FIGS. 5 and 7, the holder portion 11 has a slit 11c extending in the sheet width direction at one end in the vertical direction. One end of the band 12 is passed through the slit 11c. One end of the band 12 passes through the slit 11c and wraps around the end of the holder part 11, and then is sewn onto the band 12 and fixed. Thereby, the holder part 11 is rotatably assembled to the end of the band 12.

As shown in FIG. 7, the other end of the band 12 wraps around the rotating shaft 5 and is then sewn and fixed to the band 12. Thereby, the band 12 is wound around the rotating shaft 5 so as to be rotatable around the rotating shaft 5. Thereby, as shown in FIGS. 3 and 6, when the bottle holder 10 is not in use, the holder part 11 can be raised upward by rotation of the band 12 and stored in the storage part 3a of the table 3.

As shown in FIG. 8, when the holder portion 11 is stored in the storage portion 3a, the holder portion 11 is held in position within the storage portion 3a by fitting with the locking claw 3b. Therefore, even if the table 3 is tilted backward, the holder part 11 rotates backward while rotating the band 12 integrally with the table 3. In this way, the band 12 can cause the holder part 11 to follow the rotation of the table 3, so as not to inhibit the rotation of the table 3. When the seated person hooks the plastic bottle 7 on the holder part 11 or takes it out, by moving the holder part 11 in the rotational direction, the holder part 11 can be moved from the position shown in FIG. It can be moved to a position closer to the seated person. Thereby, the plastic bottle 7 can be easily attached and detached from the holder part 11.

Further, the band 12 is configured to be slidable in the seat width direction along the rotating shaft 5. Thereby, as shown in FIG. 4, the bottle holder 10 can be moved to any position in the sheet width direction within the region where the rotating shaft 5 extends. This allows the bottle holder 10 to be moved to the center in the width direction of the seat when a person sitting in the rear seat opens their legs, or to move the bottle holder 10 to the opposite side when there is another person sitting next to them. You can The bands 12 that have moved to each end of the rotating shaft 5 in the seat width direction are restricted from moving in the seat width direction by hitting the tips of each arm 4, respectively.

In addition, when moving the bottle holder 10 in the seat width direction, if the holder part 11 interferes with luggage (not shown) provided in the pocket 8 provided at the lower back of the seat back 2, the holder part 11 may be moved upward. Interference with the above-mentioned baggage can be avoided by rotating it. Therefore, the bottle holder 10 can be moved smoothly in the seat width direction. As described above, the bottle holder 10 is convenient for rear seat occupants because the band 12 is slidable in the seat width direction with respect to the rotation axis 5 and rotatable around the rotation axis 5. It can be easily moved to any position. Thereby, the convenience of the bottle holder 10 can be improved.

Since the band 12 is made of leather, when the band 12 is passed through the slit 11c or wound around the rotating shaft 5, it can be flexibly bent or slid to fit these shapes. Thereby, as shown in FIG. 7, the band 12 can be easily passed through the narrow slit 11c or the narrow gap between the rotating shaft 5 and the table 3. In this way, the band 12 can be wound around the bottle holder 12 through a narrow space, so that the structure in which the bottle holder 10 is provided at the lower part of the table 3 can be made more compact, and space can be saved.

To summarize the above, the seat 1 according to the first embodiment has the following configuration. In addition, in the following, the symbols shown in parentheses are the symbols corresponding to each structure shown in the above embodiment.
