DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the steering wheel cover 11 includes a pair of elastic cushion portions 12 and 13 and a pair of cushion portions 12 and 13.
And a flexible connecting portion 14 for connecting at a predetermined interval.
And a hooking portion 16 whose both side edges are connected to the side edges of the pair of cushion portions 12 and 13, respectively. The cushion parts 12 and 13 have cushion bodies 12a and 13a formed in a rectangular parallelepiped shape, and cushion skins 12b and 13b that cover the cushion bodies 12a and 13a (FIG. 1). The cushion bodies 12a and 13a are made of elastic polyurethane foam resin, polystyrene foam, sponge rubber, air bag, or the like. The outer dimensions of the cushion bodies 12a and 13a are 1.0D to 1.2 when the outer diameter of the steering wheel 17 is D.
D, preferably 1.0D to 1.1D, with a width of 0.3
D to 0.4D, preferably 0.33D to 0.38D, and further 30 to 70 mm in thickness, preferably 40 to 60.
mm. The outer dimensions of the cushion portions 12 and 13 are very thin because the cushion skins 12b and 13b are very thin.
It is determined by the outer dimensions of the cushion bodies 12a and 13a.

The length of the cushion bodies 12a and 13a is limited to the range of 1.0D to 1.2D. When the length of the cushion bodies 12a and 13a is less than 1.0D, a part of the steering wheel 17 is exposed when the steering wheel 17 is covered. There is a bug,
This is because if it exceeds 1.2 D, the size becomes unnecessarily large and the manufacturing cost is increased. Further, the widths of the cushion bodies 12a and 13a are limited to the range of 0.3D to 0.4D because if the width is less than 0.3D, the legs of the driver cannot be held in a stable state and the steering wheel 17 is covered. There is a problem that the dimension cannot be secured, 0.4D
This is because there is a problem in that the manufacturing cost exceeds the necessary value and the manufacturing cost is increased. Furthermore, the cushion body 12
The thicknesses of a and 13a are limited to the range of 30 to 70 mm. When the thickness is less than 30 mm, there is a problem that a predetermined cushioning property cannot be obtained and a predetermined height cannot be obtained when used as a bed pillow. This is because if it exceeds 70 mm, it becomes unnecessarily large and the manufacturing cost is increased.

On the other hand, the connecting portion 14 in this embodiment has a connecting body 14a formed in a rectangular plate shape and a connecting skin 14b covering the connecting body 14a (FIG. 1). The connection body 14a is made of flexible cotton, felt, sponge rubber, or the like. The external dimensions of the connection body 14a are 1.0D to 1.2D in length, preferably 1.0D to 1.1D, and 0.45D in width.
The thickness is 0.60D, preferably 0.50D to 0.55D, and the thickness is thinner than the cushion bodies 12a and 13a and is 10 to 20 mm, preferably 12 to 17 mm. The external dimensions of the connecting portion 14 are determined by the external dimensions of the connecting body 14a because the connecting skin 14b is extremely thin. Further, by setting the width of the connecting body 14a to the above size, the connecting portion 14 is configured to connect the pair of cushion portions 12 and 13 with an interval of 0.45D to 0.60D. Further, the connecting portion may be configured by using only the connecting skin without using the connecting body. In this case, the connecting portion has a thickness of several mm or less, and the steering wheel cover is used as a bed pillow to be described later. There is almost no difference in height when folded in two.

The length of the connecting body 14a is 1.0D to 1.2.
Limiting to the range of D is that if it is less than 1.0D, there is a problem that a part of the steering wheel 17 is exposed when it is covered with the steering wheel 17, and if it exceeds 1.2D, it becomes unnecessarily large and is manufactured. This is because there is a problem that pushes up costs. The width of the connecting body 14a is 0.4
The range of 5D to 0.60D is limited to less than 0.45D because it cannot be folded in three when used as a bed pillow and a dimension for covering the steering wheel 17 cannot be secured. ., 0.60D, there is a problem that it becomes unnecessarily large and pushes up the manufacturing cost. Further, the thickness of the connecting body 14a is 10
The range limited to 20 mm is less than 10 mm,
There is a problem that the amount of height adjustment when using it as a bed pillow is too small, and if it exceeds 20 mm, it becomes difficult to bend the connecting portion 14 and it becomes larger than necessary, increasing the manufacturing cost. Because there is. The cushion skins 12b and 13b and the connection skin 14b
Is formed by sewn the pair of cushion bodies 12a, 13a and the coupling body 14a wrapped with a flexible sheet such as cloth, non-woven fabric or vinyl chloride leather (FIG. 1).

As shown in detail in FIGS. 1 and 3, the hook portion 16 is formed of a sheet having the same flexibility as the cushion skins 12b and 13b and the connecting skin 14b. One side edge of the hook portion 16 is sewn (connected) to the outer edge of one cushion skin 12b, and the other side edge is sewn (connected) to the outer edge of the other cushion skin 13b. Further, the base end edge of the hook portion 16 is a pair of cushion skins 12.
It is sewn (connected) to the base end edges of b and 13b and the base end edge of the connecting skin 14b, and the tip end edge is formed in a substantially inverted V shape and is opened without being sewn. As a result, the hook 16
Is the back surface of the pair of cushion portions 12 and 13 and the connecting portion 14.
Is formed in a pocket shape that covers most of the back surface of the.

Further, the hooking portion 16 is constructed so that it can be hooked on the back surface of the steering wheel 17 when the pair of cushion portions 12, 13 and the connecting portion 14 are spread and covered on the front surface of the steering wheel 17 (FIG. 1). And Figure 2). The leading edge of the hooking portion 16 is formed in a substantially inverted V shape because the pair of cushion portions 12, 13 and the connecting portion 14 are spread to cover the surface of the steering wheel 17, when the pair of cushion portions 12, 13. 13 and connection part 1
Before the surface of the steering wheel 17 is completely covered by the steering wheel 4,
This is for avoiding a part of the surface of the steering wheel 17 being exposed by coming into contact with the steering column cover 18 located in the center of the steering wheel.

A first method of using the steering wheel cover thus configured will be described with reference to FIGS. 1 to 3. When the vehicle is parked in a parking lot and the driver is away from the vehicle for a comparatively long time, the driver needs to use a pair of cushion parts 1
2 and 13 and the connecting portion 14 are spread and covered on the front surface of the steering wheel 17, and the hook portion 16 is hooked on the back surface of the steering wheel 17. As a result, the surface of the steering wheel 17 has a pair of cushion portions 12, 13
And since it is kept covered by the connecting portion 14,
Direct sunlight is not applied to the steering wheel 17, and the pair of cushion bodies 12a, 13a and the connecting body 14a heat the steering wheel 1 due to the sunlight.
It functions as a heat insulating material that blocks the transmission to 7. As a result, the temperature of the steering wheel 17 can be prevented from rising, and the driver can operate the steering wheel 17 immediately by removing the steering wheel cover 11 from the steering wheel 17 without waiting for the steering wheel 17 to cool. You can start driving the vehicle.

When the driver takes a nap while sitting in the driver's seat, first, the pair of cushion portions 12 and 13 and the connecting portion 14 are expanded to cover the surface of the steering wheel 17, and the hook portion 16 is attached to the steering wheel 17.
On the back of the. Next, after the driver is seated in the driver's seat and the seat back is tilted backward, both legs are placed on the pair of cushion portions 12 and 13, respectively. At this time, since the contact area of the leg cushions 12 and 13 is relatively large, the part of the leg contacting the cushion portions 12 and 13 does not hurt, and in this state, the driver takes a nap for a relatively long time. can do. When the steering wheel cover 11 is put on the steering wheel 17, the base end edge of the hook portion 16 and the pair of cushion portions 1 are provided.
The connecting portions of the base end edges 2 and 13 and the base end edge of the connecting portion 14 abut on the upper end of the steering wheel 17, so that the steering wheel cover 11 causes the steering wheel 1 to move.
The pair of cushion parts 12 and 1 without falling off
3 and the connecting portion 14 are securely held in a state of covering the surface of the steering wheel 17.

Next, a second method of using the steering wheel cover of the present invention will be described with reference to FIG. Attach the steering wheel cover 11 to the pair of cushion parts 12,
The seats 13 are placed on the seat cushion 31a of the driver seat 31 so that the seats 13 are arranged in the vehicle width direction. That is, the steering wheel cover 11 is seated on the seat cushion 3 of the driver seat 31 so that the pair of seat cushion portions 12 and 13 and the connecting portion 14 are expanded and the pair of cushion portions 12 and 13 are aligned in the vehicle width direction.
Place on top of 1a. The driver operates the steering wheel cover 1
When the vehicle makes a sharp turn while seated on the seat 1, the buttocks of the driver try to shift in the direction in which the centrifugal force acts (for example, the one cushion part 12 side), but one cushion part thicker than the connecting part 14 12 serves as a wall to prevent the driver's buttocks from shifting. As a result, the driver can always drive in a stable state regardless of the driving situation. When the seat is the passenger seat, the passenger seated in the passenger seat can always continue to sit in a stable state.

A third method of using the steering wheel cover of the present invention will be described with reference to FIGS. By folding the steering wheel cover 11 at three side edges of the connecting portion 14 of the steering wheel cover 11, the steering wheel cover 11 is folded in three (FIGS. 5 and 6), or at the center of the connecting portion 14. Folding the steering wheel cover 11 in two (FIG. 7), the vehicle is mounted on the vehicle and at a predetermined position of the bed 51 provided behind the driver's seat (a position facing the head of the occupant 52 who takes a nap in the bed 51). Put on.

When the steering wheel cover 11 is folded in three as described above, a pair of cushion portions 12 and 13 are formed.
Also, since the connecting portion 14 is vertically stacked, the height when the steering wheel cover 11 is used as a bed pillow is increased. As a result, the occupant 52 who prefers to sleep with the pillow relatively high can comfortably take a nap in the bed. On the other hand, when the steering wheel cover 11 is folded in two as described above, a pair of cushion portions 12,
Since 13 is vertically stacked, the height when the steering wheel cover 11 is used as a bed pillow is reduced. As a result, an occupant who prefers to sleep with the pillow relatively low can comfortably take a nap in the bed 51.
In this way, the steering wheel cover 11 can be used as a bed pillow that can be adjusted to a height according to the preference of the occupant 52 who takes a nap on the bed 51.

[0021]

As described above, according to the present invention, a pair of elastic cushion portions are connected by a connecting portion at a predetermined interval, and the back surfaces of the pair of cushion portions and the back surface of the connecting portion are connected to each other. Since both side edges of the hook portion covering at least a part are respectively connected to the outer edges of the pair of cushion portions, the pair of cushion portions and the connecting portion are expanded to cover the front surface of the steering wheel, and the hook portion is attached to the rear surface of the steering wheel. The steering wheel surface is held in a state of being covered by the pair of cushion portions and the connecting portion. As a result, the irradiation of direct sunlight on the steering wheel is blocked, and the pair of cushion portions function as heat insulating materials, so that the temperature rise of the steering wheel can be prevented. Also, when the driver takes a nap while sitting in the driver's seat, the driver may put both legs on a pair of cushions, respectively.
Since the contact area of the legs with the cushion portion is relatively large, the driver can take a nap for a relatively long time in this state.

Further, by connecting the base end edges of the hooking portions to the base end edges of the pair of cushion portions and the base end edges of the connecting portions to form the hooking portions in a pocket shape, the pair of cushion portions and connecting portions can be formed. When unfolded and covered on the surface of the steering wheel, and when the hook is hooked on the back of the steering wheel, the connection between the base edge of the hook, the base edges of the pair of cushions, and the base edge of the connecting part Since it abuts on the upper end of the steering wheel, the pair of cushion portions and the connecting portion are securely held in a state of covering the surface of the steering wheel.

If the pair of cushion portions are placed on the seat cushion of the seat so as to be lined up in the vehicle width direction, and if the occupant sits on the seat cushion, the pair of cushion portions will move to the buttocks of the occupant even if the vehicle makes a sharp turn. It is possible to prevent displacement in the vehicle width direction.
As a result, the occupant sitting on the seat can always drive in a stable state or can continue to sit. Further, if the folding is performed at each side edge of the connecting portion to fold it in three, or at the center of the connecting portion to fold it in two, the steering wheel cover can be raised to suit the preference of an occupant who sleeps in bed. Since it can be used as a bed pillow with adjustable height, the occupant can comfortably take a nap in the bed.
