Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a seat for a motorcycle or the like in which various adjustment mechanisms such as a side support and a reclining mechanism are provided, in which these adjustment mechanisms are integrated into a single operating member. Concerning what is adjusted by.

[Prior Art] There are seats with a 112-wheel load line that are equipped with various adjustment mechanisms such as a horizontal boat and a reclining mechanism. In this case, each adjustment mechanism has an operation member such as a rotary knob for performing the respective adjustment operation, and these operation members are separately arranged around the seat.

[Problems to be Solved by the Invention] In the above-mentioned conventional example, operating members such as knobs for various adjustment mechanisms must be separately arranged around the seat, and a plurality of knobs must be arranged within a limited seat space. Operating members such as these must be arranged so as not to impair the comfort of the occupants. However, this makes layout design extremely difficult. Furthermore, operating a plurality of operating members becomes cumbersome for the occupant, and the sense of comfort is impaired.

Therefore, an object of the present invention is to solve this problem by concentrating the adjustment means of each adjustment mechanism into a single operating member.

[Means for Solving the Problems] The seat adjustment device of the present invention has the following configuration. In a seat having a plurality of adjustment mechanisms, a single unit that applies a driving force to adjust the adjustment mechanisms is provided. a rotational drive means and a switching means for switching a transmission path of rotational force by the rotational drive means to any one of the plurality of adjustment mechanisms on the same axis. It is characterized by being

[Operation of the Invention] In the seat adjustment device according to the present invention, the adjustment means of each adjustment mechanism are concentrated in a single operating member. Further, this operating member has a rotary drive means and a switching means coaxially. When the former is rotated, the adjustment mechanism connected thereto is actuated to perform appropriate adjustment operations. Furthermore, when the latter switching means is operated to switch the transmission path, the transmission of the rotational driving force by the rotational driving means is changed to another adjustment mechanism.

[Example] Figures 1 to 8 show an example in which the present invention is applied to a motorcycle seat.

FIG. 1 shows a motorcycle seat to which the present invention is applied.

This seat S is a two-person seat and has a front seat Sf and a rear seat Sr. However, the front seat Sf and the rear seat Sr are manufactured separately, and a backrest sb is provided between them. Inside the backrest sb, there is a side support unit 1.
is provided, and a pair of side support plates 2a and 2b are attached to both ends thereof so as to be expandable. Furthermore, an adjustment unit 10 that integrates a slide mechanism 3 and a reclining mechanism 4 is provided below the rear seat Sr. Also, on the side of the front seat Sf below the backrest sb,
An operating member 5 consisting of a knob or the like is fixed. This position is within the range that can be operated by the occupants of the front seat Sf and the rear seat Sr. The operating member 5 is used to adjust the amount of expansion of the side support plate 2, and also performs adjustment operations of a slide mechanism and a reclining mechanism, which will be described later.

FIG. 2 shows the arrangement structure of the adjustment mechanism, etc. First, the support member 6 of the side support unit 1 has a box shape with a U-shaped cross section, and is fixed to the bottom plate 7 of the backrest sb by bolting. An adjustment mechanism 8, the details of which will be described later, is provided inside this support member 6, and a transmission cable 9 connected thereto passes through the bottom of the rear seat Sr, enters the vehicle body frame (not shown) below the rear seat Sr, and enters the operating member. 5.

Further, an adjustment unit 10 is provided below the rear seat Sr. The adjustment unit 10 is a slide mechanism 3 which will be described later.
and a reclining mechanism 4, and a bracket lla is pivotally attached to the tip of an arm 11 formed protruding from its front part by a shaft 12, and the lower end of the bottom plate 7 is fixed here. . Furthermore, a transmission cable 14 for the slide mechanism 3 and a transmission cable 13 for the reclining mechanism 4, which will be described later, are connected to the adjustment unit 10, respectively. Like the transmission cable 9, these transmission cables 13 and 14 are bent and housed in the vehicle body frame below the rear seat Sr and reach the operating member 5. Note that this operating member 5 is integrated into a housing 15 that is fixed to a side frame of the seat or the like. A gear mechanism (described in detail later) for rotating the operating member 5 is built into the housing 15, and the rotational force of the operating member 5 is transmitted to each adjustment mechanism via a transmission cable. Further, the operating member 5 has a switching means, and the rotation transmission path of the operating member 5 is connected to the transmission cable 9, 13 or 14.
You can switch to Note that the transmission cable 9 is
It consists of a flexible rope cable 16 that transmits rotation applied to one end to the other end, and a covered pipe 17 that protects the cable.

The structure of each transmission cable is the same. Further, a joint pipe 19 is fixed to the rear wall 18 of the support member 6. One end of the transmission cable 9 is rotatably supported within the joint pipe 19, and its tip enters the support member 6 and is integrated with the bevel gear 20.

FIG. 3 shows the detailed structure of the side support unit 1 and the like. Bevel gears 21 and 22 are arranged to face each other and mesh with a bevel gear 20 that provides a driving force for operating the adjustment mechanism 8 . The bevel gear 21 is connected to one end of the rotating shaft 23 , and a ohm 24 is formed at the other end of the rotating shaft 23 , and its tip is rotatably supported by the wall 25 of the support member 16 .

The ohm wheel 26 matches the ohm 24, and the ohm wheel 26 is connected to the side support plate 2a.
The ohm wheel 26 is fixed to the tip of the shaft 27.
It is rotatably pivoted to the support member 6 by. On the other hand, the bevel gear 22 is connected to one end of a rotating shaft 28 , and the other end of the rotating shaft 28 is fitted into one end of a joint pipe 29 . The joint pipe 29 also fits into the other end of the rotating shaft 30, and these are integrally connected by fastening screws 31 and 32. An ohm 33 is attached to the other end of the rotating shaft 30.
is formed, and its tip is rotatably supported by the wall portion 34 of the support member 6. Ohm wheel 35 is attached to Ohm 33
The ohm wheel 35 is fixed to one end of the side support plate 2b, and rotatably attached to the support member 6 by a shaft 36. However, the ohms 24 and 33 are arranged in the same direction.

Now, point cable 9 in joint pipe 19 to arrow A.
When the bevel gear 20 rotates in the direction shown in FIG. As a result, 24 ohms
The ohm wheel 26 that meshes with the ohm wheel 26 rotates the integrated side support plate 2a in the direction of the arrow. At the same time, the side support plate 2b side also rotates in the direction of arrow E.

This narrows the gap between the left and right side support plates 2a and 2b, strongly supporting the occupant's waist. Conversely, if the distance between the side support plates 2 is widened to weaken the support for the occupant's waist, the cable 9 of the joint 19 may be rotated in the opposite direction.

Adjustment unit 1 installed in parallel with side support unit 1
0 consists of a fixed plate 37 and a slide plate 38 that is slidably housed inside the fixed plate 37, and a shaft 39 is attached to the slide plate 38 so as to cross the slide plate 38 in the left-right direction. One end of a swing plate 40 is attached to the shaft 39.

Further, a slider 41 is provided on the shaft 39. Furthermore, a threaded rod 43 is provided as a member of the slider mechanism to engage with a flanged nut 52 fixed to the rear wall of the slide plate 38. The fixed plate 37 and the slide plate 38 are connected with bolts 51 through elongated holes 50 formed at the bottom of the slide plate 38, so that the slide plate 38 can slide with respect to the fixed plate 37. Therefore, by rotating the threaded rod 43 forward and backward, the position of the slide plate 38 is adjusted so that it can move forward and backward.

Additionally, a slider 41 is used as a member of the reclining mechanism.
A threaded rod 47 is coupled to. These threaded rods 43 and 47 are connected to the transmission cables 14 and 13 at joint pipes 48 and 49 at the rear of the fixing plate 37, respectively.

Note that the joint pipe 49 is supported on the wall of the fixed plate 37 so as to be able to move in and out.

FIG. 4 shows a perspective view of the adjustment unit 10. This adjustment unit 10 includes a slide mechanism 3 and a reclining mechanism 4.
are formed as a unit, and are attached to the back side of the frame of the rear seat Sr or the vehicle body frame. The slider 41 is placed in a notch 40a provided in the swing plate 40, so that the slider 41 does not interfere with the swing of the swing plate 40. Both ends of the shaft 39 protrude into a long hole 44 formed on the side of the fixed plate 37, and its movement in the left and right direction is restricted by screws 45 and 46 fixed to the ends of the shaft. Roughly speaking, the upper end of the swing plate 40 is pivotally attached to the bottom plate 7 of the backrest Sb by a shaft 42 (see FIG. 5).

Next, the operation of the reclining mechanism 4 will be explained based on FIGS. 3 to 5. FIG. 5 shows the operation of the reclining mechanism, in which the reclining mechanism 4 has a shaft 12,
It has a link formed by the bottom plate 7, the shaft 42, the swing plate 40, the shaft 39, etc. Therefore, as shown in FIGS. 3 and 4, when the driving force is transmitted from the transmission cable 13 to the joint pipe 49 and the threaded rod 47 rotates,
The slider 41 that engages with this is moved back and forth, and at the same time both ends of the shaft 39, which is integral with the slider 41, are moved back and forth within the elongated hole 44. Then, as shown by the two-dot chain line in FIG.
0 also rotates around the shaft 39 to move the bottom plate 7 back and forth via the shaft 42. Therefore, the bottom plate 7 swings back and forth as shown by arrow F around the shaft 12.

FIG. 6 shows the operation of the slide mechanism 3. The threaded rod 43 is connected to the transmission cable 14 via the joint pipe 48.
When the flange nut 52 is rotated, the flange nut 52 is moved back and forth, so that the slide plate 38 to which the flange nut 52 is attached is moved back and forth with respect to the fixed plate 37. For example, when the fixed plate 37 moves forward, the bottom plate 7 also moves forward in parallel as shown by the two-dot chain line.At this time, the joint pipe 49 can move in and out of the wall of the fixed plate 37. , the reclining angle remains constant.

FIGS. 7 and 8 show the structure of the operating member 5 having a rotational drive means and a switching means. The operating member 5 consists of dials 53 and 54 that are coaxially and rotatably mounted. The dial 53 corresponds to the rotary drive means in the present invention, and the dial 54 corresponds to the switching means in the present invention.

The dial 53 is provided with a gear 55 that rotates concentrically and integrally with the dial 53.

The gear 55 meshes with a large diameter transmission gear 56.

The gear 56 is integrally provided with a concentric gear 57 having a small diameter. Note that the gear 55, the gear 56, and the gear 57 are integrated with the dial 54, and can be rotated concentrically with the rotation of the dial 54.

Therefore, it can mesh with a gear 58 located on the rotation locus of the gear 57. A bevel gear 59 is provided overlappingly with the gear 58 (described later) and meshes with a bevel gear 6o, and the bevel gear 60 is integrally connected to the cable 16 of the transmission cable 14. The cable 16 is connected to the bell gear 60 using the cable 1.
The fitting end 16a formed at the tip of 6 and the bevel gear 6
The fitting recess formed in the joint 60a of the angle 60a is fitted and integrated in a relatively non-rotatable manner. The pin 60 connects the bevel gear 60 and the joint 60a.
According to b. Note that the other transmission cables 9 and 13 have the same connection structure with each of the bell gears at their ends. When the bevel gear 60 is rotated, the cable 16
are rotated at the same time, and the other end is also rotated together, so the rotation applied to one end of the cable 16 is transmitted to the other end, and the aforementioned slide mechanism 3 is operated for adjustment.

However, in FIG. 7, the rotation of the dial 53 is transmitted through the transmission cable 13.
The reclining mechanism 4 described above is being adjusted. Incidentally, gears 61 and 62 similar to the gear 58 are disposed at the meshing position on the rotating orbit of the gear 57. Further, the dial 54 has a selector 63, and by selecting the selector 63, it is possible to switch the engagement between the gear 57 and either the gear 58, 61 or 62. In addition, gear 6
1 and 62, the rotation of the operating member 5 is transmitted by a mechanism similar to the transmission cable 14 via the transmission cables 9 and 13, respectively, to the adjusting mechanism connected to each. Dials 53, 54, each gear, and transmission cables 9, 13,
14 etc. are attached to the housing 15.

FIG. 8 is a longitudinal section of the operating member 5, showing the operation of the rotational drive means. Note that the cross section in the figure shows a gear drive structure for the transmission cable 13. Dials 53 and 54 are tIfI6
4 are installed coaxially. A gear 55 is fixed to the end of the shaft 64, and a large diameter gear 56 is meshed with the gear 55.

A small diameter gear 57 is coaxially attached to the gear 56 through a shaft 65'. Gear 57 meshes with gear 61. gear 6
1 has a bevel gear 67 coaxially integrated with it through a shaft 66. A bevel gear 68 meshes with the bevel gear 67 . The bevel gear 68 and the transmission cable 13 are connected and integrated at a joint 69. The bevel gear 68 and the joint 69 are fixedly supported by the housing 15. The plate 70 integrated with the housing 15 includes
The shaft end of the shaft 66 is attached, and the shaft 64 is also supported via a boss 71 formed on the shaft portion of the dial 54. boss 7
A collar 73 having a flange 72 is fitted around the outer periphery of the collar 1 . Plate 7° and flange 72 are connected to bolt 7
4, and the collar 73 cannot rotate relative to the housing 15. The tip of the collar 73 fits into the dial 54, and a selector 63 is formed at the joint between the two to restrict the rotation of the dial 54 in stages.

Further, the dial 54 is integrally engaged with a boss 71 at a convex portion 54a in the center thereof, and as the dial 54 rotates, the boss 71 also rotates integrally. The boss 71 is integrated with a gear box 76 by bolts 7'), and gears 55, 56, and 57 are pivotally attached to the gear box 76. Therefore, as the boss 71 rotates, the gearbox 76 also rotates around the shaft 64. The dial 53 is integrated with the shaft 64 and can rotate independently of the dial 54. When the dial 53 is rotated, the shaft 64 also rotates together, causing the gear 55 to rotate. As a result, dial 53 → shaft 64 → gear 55 → gear 56 →
Shaft 65 → Gear 57 → Gear 61 → Shaft 66 → Bevel gear 6
7→The rotation is transmitted to the bevel gear 68, and the reclining mechanism 4 is further adjusted via the transmission cable 13.

According to this embodiment, three adjustment mechanisms consisting of a side support unit 1, a slide mechanism 3, and a reclining mechanism 4 are provided, and all of these mechanisms can be operated with a single operating member 5, resulting in extremely excellent operability. You will get a comfortable seat. Furthermore, since a flexible transmission cable is used to transmit the rotational force of the operating member 5, the operating member can be placed in any desired location, increasing the degree of freedom in layout.

[Effects of the Invention] Since the present invention has a rotary drive means and a switching means coaxially, the adjustment operation member can be concentrated into a single member even though it has a plurality of adjustment mechanisms. Therefore, it is sufficient to provide only one operating member for a seat that can be adjusted in a plurality of types, which facilitates layout design. Moreover, the passenger only needs to operate a single operating member.
Operation becomes easier and comfort increases.
