Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to the structure of an armrest for an automobile seat that has a built-in storage section that opens outward.

(Prior Art) Some conventional automobile seats are provided with an armrest on the side of the seat back. Furthermore, recently, armrests with internal storage compartments for storing telephones and other small items have been used (for example, Japanese Patent Laid-Open No. 60-36742,
(Refer to Japanese Utility Model Application Publication No. 60-36743).

However, in these conventional structures, the end of the lid that opens and closes the opening of the storage section is generally rotatably attached to the edge of the opening, and the user has to manually close the lid. They either have a so-called door-type structure that opens and closes by rotating them toward you, or they have a removable structure that allows you to completely remove the lid from the main body. Moreover, in the case of a door type, there is an inconvenience that not only does the lid require a space to rotate, but also the user must make large movements to open and close the lid.

(Purpose of the invention) In view of the above circumstances, the present invention provides a structure in which the opening of the storage part can be opened and closed with a simple operation without taking up space in an armrest for an automobile having a storage part inside. The purpose is to

(Structure of the invention) The present invention provides an armrest that is rotatably supported on the side of the seat back of an automobile seat and that has a storage section that opens outward. It includes a shaft that is pivotally supported, and a lid that is fixed at one end to the shaft and has an engaging portion at the other end and is wound up by rotation of the shaft to open and close the opening of the storage section, and the lid opens and closes the opening of the storage section. The armrest main body has a locking part that locks the engaging part in a state where the lid is covered, and a biasing means that biases rotation of the shaft in a direction in which the lid is rolled up. Note that the shaft may be provided with a braking means for braking the rotation of the shaft due to the urging force of the urging means.

According to such a configuration, the opening of the storage portion is closed by pulling out the lid against the urging force of the urging means to cover the opening and locking the engaging portion with the locking portion of the armrest main body. When this engagement is released, the shaft rotates under the urging force of the urging means, and the lid is rolled up at a predetermined speed, opening the opening. .

(Example) Embodiments of the present invention will be described based on the drawings.

FIG. 1 shows an automobile seat consisting of a seat cushion 1 and a seat bag 2 that rotates relative to the seat cushion 1. As shown in FIG. The seat back 2 is provided with a rotation shaft (not shown) projecting from its side, and supports an armrest 3 rotatably about this rotation shaft. This rotation shaft is provided with appropriate stopper means for stopping the rotation of the armrest 3 at three positions: a forward protruding position, a substantially vertical position, and a rear protruding position as shown in the figure.

As shown in FIG. 2, this armrest 3 consists of a frame 3a, a pad 3b, and a skin 3c covering these.Furthermore, inside the armrest 3, there is a tray 4 whose bottom surface is fixed to the frame 3a, and a tray 4 that is fixed to the frame 3a. It has a storage section 5 for storing small items etc., which is a space between the upper openings 3b.
The storage section 5 has a structure that opens upward when the armrest 3 is in the rear protruding position (solid line in Figure 1), and is wound and rolled by a shaft 6 to open and close the opening 3d of the storage section. A lid 7 is provided on the armrest 3. Furthermore, a protrusion 8 (locking part) for locking the end of the lid 7 covering the opening 3d is provided at the edge of the opening 3d on the end side of the armrest 3. There is.

The shaft 6 extends in the width direction at the base of the armrest 3, and both ends are pivotally supported by the armrest 3 main body. The lid 7 has one end connected to this shaft 6.
is fixed. As shown in FIG. 4, the main body is made of resin and has thick parts 7a and thin parts 7b alternately, and the surface is covered with a skin 7c fixed by thermal welding 9. By being formed in this way, it has the strength and elasticity to be wound up by the shaft 6.The other end of the lid 7 is provided with a mounting member 7d, and this mounting member 7d has a A hook 10 (engaging portion) that rotates around a shaft 11 is provided. A knob 10a is provided on the head of the hook 10, and the rotation of the hook 10 is biased counterclockwise in FIG. 2 by appropriate means such as a spring. Note that guides 3e for guiding the movement of the lid 7 when opening and closing are formed at both longitudinal edges of the opening 3d.

Further, as shown in FIG. 3, a spiral spring 12 (biasing means) is attached to one end of the shaft 6 to urge rotation of the shaft 6.
At the other end, there is a shaft 6 formed by this spiral spring 12.
A braking means 13 is provided for braking the rotation.

The spiral spring 12 has one end fixed to the circumferential surface of the shaft 6 and the other end fixed to the frame 3a of the armrest 3. This spiral spring 12
urges the rotation of the shaft 6 in the direction of winding up the lid 7 (see the arrow in FIG. 2).

The braking means 13 consists of a gear 14 fixed to the shaft 6, a gear 15 meshing with the gear 14, and a damper 16 housing the gear 15 with the meshing portion remaining and attached to the inner wall of the armrest 3. There is. When the gear 14 rotates together with the shaft 6, the gear 15 meshing with the gear 14 rotates in the oil 17 within the damper 16. This brakes the rotation of the shaft 6 due to the biasing force of the spiral spring 12, and prevents the lid 7 from accelerating and impacting the frame 3a etc. in the latter half of winding.

Next, the operation of the above device will be explained. First, the second
As shown in the figure, with the lid 7 closed, the armrest 3 is rotated to the rearward protruding position. In this state, when the knob 10a of the hook 10 is pushed with a finger or the like and the hook 10 is rotated around the shaft 11, the engagement between the hook 10 and the projection 8 is disengaged, and the lid 7 is moved to the guide 3e.
It is wound up by the shaft 6 while being guided by. At this time, the shaft 6 rotates under the urging force of the spiral spring 12. This rotation is braked by the braking means 13, and the lid 7 is rolled up at a low speed. In this way, the lid 7 can be opened and the items stored in the storage section 6 can be taken out.

Conversely, when closing the storage section 5, the above-mentioned knob 1
0a, pull out the lid 7 along the guide 3e against the biasing force of the spiral spring 12, and then remove the hook 1.
0 may be engaged with the protrusion 8. By rotating the armrest 3 to the forward protruding position in this closed state, the armrest 3 can be used as a normal arm rest by utilizing the surface 3f on the back side of the opening 3d.

As mentioned above, this armrest 3 has a knob 10
The storage section 5 can be opened by simply rotating the hook 10 using a.
Since it can be opened and closed, there is no need for cumbersome operations like in the past.

Note that the term "storage section" in the present invention can be applied not only to accessory cases, but also to, for example, a telephone storage box. Further, the mounting structure of the armrest 3 does not particularly need to be rotatable rearward as described above, and may be of a structure that can be tilted only forward.

(Effects of the invention) As described above, the present invention is such that in an armrest having a storage section inside, the storage section is opened and closed by a lid that is rolled up by a shaft rotated by the urging force of the urging means. The storage section can be opened and closed with a simple operation, without requiring complicated operations unlike conventional removable lids or door-type lids.

In addition, if the shaft is equipped with a braking means,
In the latter half of the winding process, the lid can be prevented from being rolled up in an accelerated state, and at this time, the lid can be prevented from impacting the armrest body.
