DETAILED DESCRIPTION OF THE INVENTION Embodiments for carrying out the invention will be described below. A rear seat assistance device 1 according to an embodiment of the present invention is attached to an automobile 2 as shown in FIGS. 1A and 1B. The rear seat assistance device 1 includes a door attachment 11, a first rod 12, a second rod 13, and a front seat attachment 14. - 特許庁1A and 1B omit the rear side door (rear side door) 3 behind the entrance/exit.

The door attachment 11 is attached to the rear side door 3 of the automobile 2 . As shown in FIGS. 2A and 2B, the door attachment 11 has a door fixing portion 11a fixed to the rear side door 3 and a rod fixing portion 11b fixed to the first rod 12. The door fixing portion 11a and the rod fixing portion 11b may be coupled (for example, by a ball joint, which will be described later) so as to be rotatable in any direction (any three-dimensional direction).

Although the specific structure of the door fixing portion 11a is not particularly limited, as shown in FIG. can.

The insertion flat plate portion 11aa is formed in the gap 3c (see FIG. 4) between the fixed glass fixing rubber 3a (see FIGS. 1A and 4) and the door inner panel 3b (see FIGS. 1A and 4) in the rear side door 3 of the automobile 2. It can be fixed to the rear side door 3 by inserting it downward (see the broken line portion in FIG. 1A). The insertion flat plate portion 11aa can be sandwiched between the fixed glass fixing rubber 3a and the door inner panel 3b and firmly fixed by their elasticity. The insertion flat plate portion 11aa has a thickness of, for example, about 2 mm to 3 mm. The fixed glass fixing rubber 3a fixes the rear fixed glass 3f of the elevating glass 3e and the fixed glass 3f separated by the division bar 3d of the rear side door 3 (see FIG. 1A).

The ball joint support portion 11ab is provided continuously with the insertion flat plate portion 11aa and supports the ball joint main body portion 11ac, which will be described in detail later. The ball joint support portion 11ab extends horizontally (horizontal direction in FIGS. 2(a) and 2(b)) when the insertion flat plate portion 11aa is fixed to the rear side door 3. As shown in FIG. The length K extending in the horizontal direction is such that when the rear side door 3 is opened at a desired angle (90 degrees in FIGS. 1A and 4), the division bar 3d and the like do not interfere with the first rod 12, which will be described in detail later. length. Also, the ball joint main body portion 11ac can be fixed to the ball joint support portion 11ab by a fixture (see FIG. 3). A cushioning material may be arranged below the ball joint support portion 11ab between the rear door inner panel 3b and the ball joint support portion 11ab.

The ball joint main body portion 11ac has a spherical portion (see the dashed line portion in FIG. 3 and the solid line portion that is slightly exposed below it), and when the insertion flat plate portion 11aa is fixed to the rear side door 3, the upper portion is spherical. part is located.

Although the specific structure of the rod fixing portion 11b is not particularly limited, it can have a ball joint movable portion 11ba and a rod fixing portion 11bb.

The ball joint movable portion 11ba is a portion that is connected to the spherical portion of the ball joint main body portion 11ac so as to be rotatable in any direction by making spherical contact (that is, a ball joint) (see the broken line portion in FIG. 3).

The rod fixing portion 11bb is a portion to which the first rod 12 is fixed. If the first rod 12 has a pipe shape as described later, the rod fixing portion 11bb can be inserted into the hollow portion and fixed with an adhesive or a fixture (see FIG. 3). See the dashed line on the right).

The first rod 12 is a long rod and fixed to the door attachment 11 . The first rod 12 can be fixed to the door attachment 11 as described above.

The first rod 12 can be pipe-shaped (eg, with an outer diameter of about 30 mm). Then, the first rod 12 has a high strength, and a second rod 13 (for example, an outer diameter of about 28 mm), which will be described in detail later, is inserted through the hollow portion of the first rod 12 so that it can be easily slid in the longitudinal direction. can be combined. As a result, the length of the outer surface of the first rod 12 arranged on the side of the rear side door 3 of the automobile 2 is long (for example, about 700 mm to 900 mm), and the length does not change, so the user can When getting on and off the rear seat 5 of the automobile 2, the user can get on and off while holding the outer surface of the first rod body 12 having a uniform thickness and changing the grip. The outer surface of the first rod 12 preferably has a circular cross-section from the viewpoint of ease of holding by the user.

As shown in FIG. 2(c), the first rod 12 can be wound with a plurality of reflective tapes 12A at intervals. Then, when the rear side door 3 of the automobile 2 is opened, it is easy for the user to visually recognize it, and it is easy to call attention to a two-wheeled vehicle or the like that is about to pass by the side of the automobile 2 . Also, the reflective tape 12A is preferably yellow in order to attract attention.

The second rod 13 is coupled to the first rod 12 so as to be slidable in its longitudinal direction. The second rod 13, like the first rod 12, can be pipe-shaped. The exposed length of the second rod 13 (the length protruding from the first rod 12) L is preferably short (for example, 50 mm to 200 mm when the rear side door 3 is closed).

The materials of the first rod 12 and the second rod 13 are not particularly limited as long as they can withstand the force of the user. Examples include metals such as steel and aluminum alloys, plastics, and carbon fiber materials. is possible.

The front seat attachment 14 is fixed to the second rod 13 . Also, the front seat attachment 14 is attached to the front seat backrest 4 of the automobile 2 . Specifically, the front seat attachment 14 can be attached to a handrail 4 a provided on the back of the front seat backrest 4 .

The front seat attachment 14 has a rod fixing portion 14a and a front seat mounting portion 14b. The rod fixing portion 14 a is a portion fixed to the second rod 13 . The specific structure of the rod fixing portion 14a is not particularly limited. can be Although the specific structure of the front seat attachment portion 14b is not particularly limited, it may be hook-shaped so that it can be attached by being hooked on the handrail 4a.

In the rear seat assistance device 1 having such a configuration, the first rod 12 (and the second rod 13 and the front seat attachment 14) can be rotated in any direction with respect to the door fixing portion 11a of the door attachment 11. It is movable, and the exposed length L of the second rod 13 is variable. As a result, the rear seat assistance device 1 can change its shape following the opening and closing of the rear side door 3, as shown in FIG. When the rear seat assist device 1 is attached to the automobile 2, a user such as an elderly person or a physically handicapped person can get on and off the rear seat 5 of the automobile 2 by holding the outer surface of the first rod 12. It is possible to reduce the burden on attention and physical strength. Also, the user can hold the outer surface of the first rod 12 as a support while the automobile 2 is running.

1A, 1B, and 4 show the left rear side door 3 as an example. FIG. 4 also shows the opening and closing of the rear side door 3, showing the fixed glass fixing rubber 3a and the door inner panel 3b located near the door fixing portion 11a of the door attachment 11 and the door inner panel 3b. A gap 3c between is also shown.

Although the rear seat assistance device that is the embodiment of the present invention has been described above, the present invention is not limited to the one described in the embodiment, and various modifications within the scope of the matters described in the claims are possible. design changes are possible. For example, the rear seat assistance device may be one that can be retrofitted to a manufactured vehicle or one that is installed during the manufacturing process of the vehicle.
