Summary of the Invention

Problems to be Solved by the Invention

[0004] In the configuration described in Patent Document 1, the assembly load for fitting the lever handle to the insertion portion of the lever body is high. The reason is that it is necessary to fit the lever handle to the lever body without play from the tip to the base end, but it is necessary to set a draft angle for facilitating the removal after injection molding for the lever handle.

[0005] In other words, if the gap at the base end into which the lever body of the lever handle is inserted is narrowed, the gap at the tip will be further narrowed, increasing the assembly load required to fit the lever body. Therefore, the present invention provides a seat operating lever that allows the lever body to be assembled to the lever handle with a relatively small assembly load, thereby suppressing looseness. [Means for solving the problem]

[0006] To solve the above problems, the seat operating lever of the present invention employs the following means.

[0007] In other words, the first invention of the present invention is a seat operating lever having a metal lever body for operating a seat adjuster and a resin lever handle fitted to an insertion portion at the tip of the lever body, wherein the lever handle has an insertion portion into which the insertion portion can be inserted in the lever forward direction extending from the insertion portion, a first contact portion that abuts the insertion portion inserted into the insertion portion from both sides in the lever width direction, and a pair of upper and lower second contact portions that abut the insertion portion from both sides in the lever width direction at each position outside the vertical direction of the lever which is a virtual extension region that extends the first contact portion in the lever rear direction.

[0008] According to the first invention, even if a withdrawal angle is set in the formation region of the first contact portion that is inclined in the lever width direction toward the rear of the lever, the influence of this withdrawal angle can be prevented from affecting the pair of upper and lower second contact portions. As a result, the pair of upper and lower second contact portions can be brought into contact with the insertion portion from both sides in the lever width direction with the same gap as the first contact portion. Consequently, the lever body can be assembled to the lever handle with a relatively small assembly load to suppress looseness.

[0009] The second invention of the present invention is a seat operating lever in which, in the first invention described above, the lever handle further comprises a bottom surface extending parallel to the front-rear direction of the lever that contacts the bottom surface extending parallel to the front-rear direction of the lever of the insertion part, and a pair of front and rear upper pressing parts that protrude so as to be pressed against two positions in the front-rear direction of the lever on the top surface extending parallel to the front-rear direction of the lever of the insertion part.

[0010] According to the second invention, the position and shape of the front and rear pair of upper pressing portions can be set relatively easily, using the bottom surface of the lever handle, which is the surface against which the lower surface of the insertion portion of the lever body is made contact, as a reference.

[0011] The third invention of the present invention is a seat operating lever in which, in the first or second invention described above, the lever handle further comprises a groove into which a claw portion formed in the insertion portion snaps into place as the lever is inserted in the forward direction of the insertion portion, and a spring portion that applies an elastic force to the insertion portion in the rearward direction of the lever.

[0012] According to the third invention, the insertion portion of the lever body can be assembled to the lever handle in a manner that appropriately suppresses looseness in both the forward direction (insertion direction) and the backward direction (removal direction).

[0013] The fourth invention of the present invention is a seat operating lever in the first or second invention described above, wherein the lever handle further has a restricting surface extending parallel to the vertical direction of the lever that restricts the maximum insertion position of the insertion portion in the forward direction of the lever by surface contact with a stopper surface extending parallel to the vertical direction of the lever of the insertion portion.

[0014] According to the fourth invention, the maximum insertion position of the lever body insertion portion relative to the lever handle insertion portion can be appropriately restricted. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0016] Hereinafter, the mode for carrying out the present invention will be described with reference to the drawings.

[0017] 《First Embodiment》 (Schematic Configuration of Seat Operation Lever) First, the configuration of the seat operation lever according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 10. In the following description, when indicating each direction such as front, rear, up, down, left, and right, the respective directions shown in each figure shall be referred to. Also, in the following description, when no specific reference figure is shown, or when there is no reference numeral corresponding to the reference figure, any one of FIGS. 1 to 10 shall be appropriately referred to.

[0018] As shown in FIG. 1, the seat operation lever according to the present embodiment is configured as a lifter lever 1 disposed on the left side surface of a seat S that forms the left seat of an automobile. The lifter lever 1 is configured as an operation lever for a seat lifter L provided on the seat S to adjust the height position of the seat S. Here, the seat lifter L corresponds to the "seat adjuster" of the present invention. Note that the seat lifter L has the same configuration as a known configuration disclosed in documents such as Japanese Patent Application Laid-Open No. 2021-181281. Therefore, the description of the specific configuration of the seat lifter L will be omitted.

[0019] Specifically, the lifter lever 1 has a metal lever body 2 connected to the seat lifter L and a resin lever handle 3 assembled to the tip of the lever body 2. The lever body 2 is passed through the seat side shield SH so as to be pulled out from the inside to the outside of the shield. The lever handle 3 is assembled to a portion at the tip of the lever body 2 pulled out outside the seat side shield SH of the lever body 2.

[0020] When the user performs an operation of grasping and lifting or lowering the lever handle 3 by hand, the operating force is transmitted to the seat lifter L via the lever body 2. Thereby, the lifter lever 1 operates the seat lifter L according to the operated direction. The rear end portion of the lever body 2 of the lifter lever 1 is connected to the seat lifter L so as to be rotatable about an axis (not shown) extending in the seat width direction.

[0021] As shown in FIGS. 2 to 5, the lever handle 3 is assembled integrally with the lever body 2 by being inserted into the lever body 2 from the front direction of the lever. By the above insertion, the lever handle 3 is assembled to the lever body 2 in a state where play is suppressed in each of the lever width direction, the lever vertical direction, and the lever front-rear direction.

[0022] As shown in Figures 4 and 5, the lever handle 3 is strictly inserted into the lever body 2 from the front, diagonally outward, and upward. In the following description, when we refer to the lever width direction (left-right direction), the lever up-down direction, and the lever front-back direction, we mean the respective directions relative to the lever body 2. The lever front-back direction is the direction in which the lever handle 3 is inserted into and removed from the lever body 2. The lever width direction and the lever up-down direction are directions perpendicular to the lever front-back direction, respectively.

[0023] Even though the lever handle 3 is assembled to the lever body 2 in such a way that play is suppressed in all directions, as described above, it can be assembled with a relatively small assembly load relative to the lever body 2. The specific configuration of each part of the lifter lever 1 will be described in detail below.

[0024] (Each part configuration) As shown in Figures 2 and 3, the lever body 2 is made of a pressed metal plate member. The tip of the lever body 2 that is inserted into the lever handle 3 has an insertion portion 2A that extends in the direction of the lever forward. The insertion portion 2A has a constant plate thickness in the direction of the lever width and is shaped to extend in the direction of the lever forward.

[0025] Specifically, the insertion portion 2A has a pair of protrusions 2B that extend in the vertical direction of the lever from its base end to its rear end. The insertion portion 2A also has an extension portion 2C that extends from the base end toward the front end to the tip end in the direction of insertion into the lever handle 3, which is the direction of the lever forward. The extension portion 2C is shaped to extend parallel to the front-rear direction.

[0026] The extension portion 2C has a shape in which the upper corner of its tip is cut off in a concave shape. As a result, the insertion portion 2A has a shape in which the dimension in the vertical direction of the lever tapers in a stepped manner from the rear end which forms the base to the front end. A claw portion 2D that protrudes to the right of the lever is formed approximately in the center of the extension portion 2C by stamping in the thickness direction of the plate. The claw portion 2D is stamped out so that an inclined rising surface faces forward of the lever and a rising surface perpendicular to the rear of the lever faces backward (see Figure 8).

[0027] The extension portion 2C has a shape in which its lower surface C3 and upper surface C4 extend parallel to the front-rear direction of the lever. More specifically, the upper surface C4 of the extension portion 2C has an upper surface portion in which the corner at its tip is cut off in a concave shape, and this portion also extends parallel to the front-rear direction of the lever. Similarly, the upper surface B1 of the upper overhang 2B also has a shape in which it extends parallel to the front-rear direction of the lever, just like the upper surface C4 of the extension portion 2C.

[0028] The front surfaces of the upper and lower protrusions 2B are formed as stopper surfaces 2G that extend parallel to the vertical direction of the lever. These stopper surfaces 2G function as surfaces that restrict the maximum insertion position of the lever in the forward direction when inserting the insertion portion 2A into the lever handle 3. The lower surface of the stopper surface 2G of the lower protrusion 2B is formed as a downward sloping surface 2H that extends diagonally downwards towards the rear.

[0029] The lever handle 3 is made of an injection-molded resin component. As shown in Figure 3, the lever handle 3 has a gripping portion 3A for the user to grasp with their hand during operation, and an insertion portion 3B that opens towards the rear of the lever so that the lever body 2 can be inserted from the rear of the lever. The direction in which the mold is removed after injection molding (mold removal direction) of the lever handle 3 is set to the rear of the lever, which is the direction in which the opening of the insertion portion 3B is located.

[0030] Accordingly, each surface of the lever handle 3 is provided with a release angle to facilitate removal after injection molding. Specifically, for example, the inner circumferential surface of the insertion portion 3B is provided with a release angle that slopes to gradually widen the width and height of its opening toward the rear of the lever.

[0031] With this configuration, the lever handle 3 has a shape in which the width and height of the opening are narrower towards the back (front of the lever) of the insertion part 3B, and become wider and taller towards the front (rear of the lever). However, even with this configuration that sets the withdrawal angle, the lever handle 3 is designed so that the insertion part 2A of the lever body 2 can be inserted into the insertion part 3B in a way that suppresses looseness.

[0032] Specifically, the insertion portion 3B has a first contact portion 3C that abuts the tip of the insertion portion 2A of the lever body 2 inserted inside it from both sides in the lever width direction, and a second contact portion 3D that abuts the base of the insertion portion 2A at two locations, upper and lower, from both sides in the lever width direction. As shown in Figure 9, the first contact portion 3C is configured to abut the tip of the insertion portion 2A of the lever body 2 from both sides in the lever width direction by being sandwiched between the right inner surface C1 of the insertion portion 3B and the first contact rib C2 that protrudes in a ridge-like manner from the left inner surface.

[0033] The right inner surface C1 of the insertion portion 3B makes surface contact with the insertion portion 2A of the lever body 2 from the right side of the lever. The first contact rib C2 is a striated projection extending parallel to the front-rear direction of the lever, and the apex of its protruding end makes linear contact with the insertion portion 2A of the lever body 2 from the left side of the lever over a wide area in the front-rear direction of the lever. More precisely, the first contact rib C2 makes surface contact with the insertion portion 2A of the lever body 2 due to its deformation caused by pressing the lever body 2 against the insertion portion 2A.

[0034] As shown in Figure 10, the second contact portion 3D is configured to contact the base of the insertion portion 2A of the lever body 2 by sandwiching it from both sides in the lever width direction, with each right inner surface rib D1 protruding in a slit-like manner from two locations on the upper and lower right inner surface of the insertion portion 3B, and each second contact rib D2 protruding in a slit-like manner from two locations on the upper and lower left inner surface. Each right inner surface rib D1 and each second contact rib D2 are slit-like projections that extend parallel to the front-rear direction of the lever.

[0035] Each right inner surface rib D1 and each second contact rib D2 have their protruding tips in linear contact with the insertion portion 2A of the lever body 2 over a wide area from the left-right direction of the lever to the front-rear direction of the lever. More precisely, each right inner surface rib D1 and each second contact rib D2 make surface contact with the insertion portion 2A of the lever body 2 due to the deformation caused by pressing the lever body 2 against the insertion portion 2A.

[0036] As shown in Figure 7, each second contact portion 3D is formed at a position offset in the vertical direction of the lever from the virtual extension region A, which is a virtual extension region in the lever-rear direction of the first contact rib C2 that constitutes the first contact portion 3C. The virtual extension region A is a region that extends in the lever-rear direction from the area that contacts the insertion portion 2A of the lever body 2 from both sides in the lever width direction by the first contact portion 3C, i.e., the right inner surface C1 of the insertion portion 3B (see Figure 9) and the first contact rib C2. With this configuration, the lever handle 3 can be formed so that the effect of the cut-out angle, which is cut out from the first contact portion 3C in the lever-rear direction, does not affect each second contact portion 3D.

[0037] In other words, since each second contact portion 3D is offset from the virtual extension region A in the vertical direction of the lever, it is possible to set the starting point of its molding process to start from a position shifted to the rear of the lever, rather than from the formation location of the first contact rib C2. As a result, even if each second contact portion 3D is positioned further rear of the lever than the first contact portion 3C, it can be formed to come into contact with the insertion portion 2A of the lever body 2 with a gap of approximately the same size as that of the first contact portion 3C.

[0038] Each second contact portion 3D is formed to contact the insertion portion 2A of the lever body 2 with a gap of approximately the same size as that of the first contact portion 3C. The first contact portion 3C and each second contact portion 3D contact the insertion portion 2A of the lever body 2 from both sides in the lever width direction, so that the lever handle 3 is inserted into the insertion portion 2A of the lever body 2 in a manner in which play in the lever width direction is suppressed.

[0039] As shown in Figure 6, the insertion portion 3B has a bottom surface 3E that abuts the lower surface C3 of the extension portion 2C of the insertion portion 2A inserted inside it, and a pair of front and rear upper contact ribs 3F that press against the two front and rear upper surfaces C4 and B1 of the insertion portion 2A. The bottom surface 3E is shaped to extend parallel to the front-rear direction of the lever and abuts the lower surface C3 of the extension portion 2C of the insertion portion 2A which extends parallel to the front-rear direction of the lever. Here, each upper contact rib 3F corresponds to the "upper pressing portion" of the present invention.

[0040] Each upper contact rib 3F is shaped to protrude from the upper surface of the insertion part 3B so as to press against the top surface C4 of the cut-off corner at the tip of the insertion part 2A that is inserted into the insertion part 3B, and the top surface B1 of the upper protrusion 2B at the base of the insertion part 2A. Specifically, as shown in Figure 9, the front upper contact rib 3F is formed to connect to the corner between the top surface of the insertion part 3B and the right inner surface C1. Also, as shown in Figure 10, the rear upper contact rib 3F is formed to connect to the corner between the top surface of the insertion part 3B and the right inner surface.

[0041] As shown in Figure 6, the bottom surface 3E of the insertion portion 3B and each upper contact rib 3F contact the insertion portion 2A of the lever body 2 from both sides in the vertical direction of the lever in a clamping manner, so that the lever handle 3 is inserted into the insertion portion 2A of the lever body 2 in a state in which play in the vertical direction of the lever is suppressed. The insertion portion 3B is shaped so that the bottom surface 3E extends parallel to the front-to-back direction of the lever, which is parallel to the die-cutting direction, and a draft angle, which is the cut-out angle during die-cutting, is formed on the upper surface.

[0042] With this configuration, the position and shape of the front and rear upper contact ribs 3F can be set relatively easily, using the bottom surface 3E of the lever handle 3, which is the surface surface C3 of the insertion portion 2A of the lever body 2, as a reference. In other words, since the insertion portion 2A of the lever body 2, which is the surface surface 3E, extends parallel to the front-rear direction of the lever, it becomes possible to set the optimal position and shape of each upper contact rib 3F relatively easily during the design phase, compared to the case where the insertion portion 2A is in an inclined position. Similarly, the position and shape of other surrounding structures can also be set relatively easily.

[0043] The insertion portion 3B described above allows the insertion portion 2A to be inserted into the insert portion 2A until the stopper surface 2G, which is the front surface of each protrusion 2B of the insertion portion 2A, makes surface contact with each regulating surface 3K that protrudes from the front end of each second contact rib D2 and faces towards the rear of the lever. Each regulating surface 3K and each stopper surface 2G are shaped to extend parallel to the vertical direction of the lever.

[0044] As shown in Figure 8, when the lever is inserted to the maximum insertion position, the claw portion 2D formed on the extension portion 2C of the insertion portion 2A snaps into the groove portion 3G formed on the right side of the insertion portion 3B. As a result, the lever handle 3 is assembled in a state in which it is prevented from coming off the lever body 2 in the lever-forward direction.

[0045] As shown in Figure 3, the groove 3G is formed in the region at the end of the flexible portion 3H, which is formed on the right side of the insertion portion 3B of the lever handle 3 and extends in a cantilever-like manner in the forward direction of the lever with the rear end of the lever as the pivot point. As shown in Figure 8, the flexible portion 3H is pushed and flexed to the right of the lever by the claw portion 2D when the insertion portion 3B of the lever handle 3 is inserted into the insertion portion 2A of the lever body 2 from the front of the lever. Then, as the claw portion 2D enters the groove 3G, the flexible portion 3H returns to its original shape due to its elastic force and hooks onto the right-angle rising surface of the claw portion 2D that faces the rear of the lever.

[0046] Furthermore, as shown in Figure 6, when the insertion portion 2A of the lever body 2 is inserted into the insertion portion 3B of the lever handle 3, the downward inclined surface 2H of the lower protrusion 2B of the lever body 2 is pressed against the spring portion 3J that extends diagonally downward and rearward from the lower edge of the lower regulating surface 3K from the rear of the lever. As a result, the lever handle 3 exerts an elastic force on the insertion portion 2A of the lever body 2, which is inserted into the insertion portion 3B, pushing it back in the rear direction of the lever.

[0047] Due to the action of this elastic force, the claw portion 2D described above in Figure 8 is pressed against the front surface of the flexible portion 3H. As a result, the lever handle 3 is inserted into the insertion portion 2A of the lever body 2 in a manner that suppresses play in the lever's front-to-back direction. With the above configuration, the lever handle 3 is assembled to the lever body 2 in a manner that suppresses play in the lever's width direction, the lever's vertical direction, and the lever's front-to-back direction.

[0048] In summary, the lifter lever 1 according to this embodiment has the following configuration. The reference numerals in parentheses below correspond to the respective configurations shown in the above embodiment.

[0049] In other words, the seat operating lever (1) has a metal lever body (2) for operating the seat adjuster (L), and a resin lever handle (3) that fits into the insertion portion (2A) at the tip of the lever body (2). The lever handle (3) has an insertion portion (3B) into which the insertion portion (2A) can be inserted in the forward direction of the lever extending from the insertion portion (2A), a first contact portion (3C) that abuts the insertion portion (2A) inserted into the insertion portion (3B) from both sides in the lever width direction, and a pair of upper and lower second contact portions (3D) that abut the insertion portion (2A) from both sides in the lever width direction at each position outside the virtual extension region (A), which is a virtual extension region that extends the first contact portion (3C) in the lever rear direction.

[0050] According to the above configuration, even if a pull-out angle is set in the forming area of ​​the first contact portion (3C) that is inclined in the lever width direction toward the rear of the lever, the effect of this pull-out angle can be prevented from affecting the pair of upper and lower second contact portions (3D). As a result, the pair of upper and lower second contact portions (3D) can be brought into contact with the insertion portion (2A) from both sides in the lever width direction with the same gap as the first contact portion (3C). Consequently, the lever body (2) can be assembled to the lever handle (3) with a relatively small assembly load to suppress looseness.

[0051] Furthermore, the lever handle (3) has a bottom surface (3E) that extends parallel to the front-rear direction of the lever and contacts the bottom surface (C3) of the insertion part (2A) that extends parallel to the front-rear direction of the lever, and a pair of front and rear upper pressing parts (3F) that protrude so as to be pressed against two positions in the front-rear direction of the lever on the top surface (C4, B1) of the insertion part (2A) that extends parallel to the front-rear direction of the lever. With the above configuration, the position and shape of the pair of front and rear upper pressing parts (3F) can be set relatively easily with reference to the bottom surface (3E) of the lever handle (3) that contacts the bottom surface (C3) of the insertion part (2A) of the lever body (2).

[0052] Furthermore, the lever handle (3) further includes a groove (3G) into which a claw portion (2D) formed on the insertion portion (2A) snaps into place as the insertion portion (2A) is inserted in the lever forward direction, and a spring portion (3J) that applies an elastic force to the insertion portion (2A) in the lever rearward direction. With the above configuration, the insertion portion (2A) of the lever body (2) can be assembled to the lever handle (3) in a state where play is appropriately suppressed in both the lever forward direction (insertion direction) and the lever rearward direction (extraction direction).

[0053] Furthermore, the lever handle (3) has a restricting surface (3K) that extends parallel to the vertical direction of the lever, which restricts the maximum insertion position of the insertion portion (2A) in the lever forward direction by surface contact with a stopper surface (2G) that extends parallel to the vertical direction of the lever of the insertion portion (2A). With the above configuration, the maximum insertion position of the insertion portion (2A) of the lever body (2) relative to the insertion portion (3B) of the lever handle (3) can be appropriately restricted.

[0054] Regarding other embodiments: Although the embodiments of the present invention have been described above using one embodiment, the present invention can be implemented in various forms other than those described above.

[0055] 1. The seat control lever of the present invention is applicable to seats installed in vehicles other than automobiles, as well as seats installed in vehicles other than automobiles, such as aircraft and ships. Furthermore, the seat control lever is applicable to seats installed in various facilities such as event venues, as well as seats other than those in vehicles, such as massage seats.

[0056] 2. The seat adjuster that the seat operation lever controls may be a seat lifter, a seat recliner, a seat slide rail, or any other type of seat adjuster.

[0057] 3. The first contact portion may be configured to be pressed against the lever in a clamping manner in the lever width direction by ribs protruding from each side, as shown in the above embodiment for the second contact portion. The lever handle may have a shape that extends parallel to the lever's front-to-back direction, with its top surface, rather than its bottom surface, making surface contact with the top surface of the insertion portion that extends parallel to the lever's front-to-back direction. In other words, the bottom surface of the lever handle may be configured to have a draft angle.

[0058] 4. The restricting structure that restricts the maximum insertion position of the insertion part by bringing the stopper surface of the insertion part into contact with the restricting surface of the lever handle may be provided at two locations, top and bottom, as shown in the above embodiment, or it may be provided at only one location, either top or bottom.
