[0002] This application claims priority to U.S. Provisional Application 63 / 215,034, filed June 25, 2021, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This invention relates to seat assemblies for use in motor vehicles. More specifically, this invention relates to a remote handle assembly configured to unlock a reclining component in a seat assembly. Background Technology

[0004] Motor vehicles typically include one or more seat assemblies having a seat cushion and a seat back for supporting passengers above the vehicle floor. The seat assembly typically includes a reclining assembly that pivotally connects the seat back to the seat cushion. It is generally known that when the reclining assembly is locked, the reclining assembly prevents the seat back from rotating relative to the seat cushion.

[0005] Furthermore, the seat assembly typically includes a remote handle assembly attached to the seat assembly and configured to selectively unlock the recliner assembly. It is generally known that the remote handle assembly includes a handle that can be rotated by an occupant and configured to actuate the remote handle assembly to unlock the recliner assembly and allow the occupant to adjust the seat back position. Additionally, it is generally known that the remote handle assembly may optionally be actuated by an electric actuator, such as when the seat assembly includes a fold-flat feature.

[0006] However, in some known remote handle assemblies, the handle attached to the assembly has excessive lateral clearance, which may be perceived by the occupant as an indication of poor quality. Additionally, some known remote handle assemblies include a covered case that supports and houses the internal components of the remote handle assembly. The case, cover, and associated fasteners increase the cost and manufacturing complexity of the remote handle assembly.

[0007] Therefore, it is desirable to provide a remote handle assembly that reduces perceived lateral looseness when the occupant rotates the handle. It is also desirable to provide a remote handle assembly with fewer parts, resulting in reduced cost and a less complex manufacturing process. Summary of the Invention

[0032] Figures 1 to 21 The illustration shows components of a seat assembly 10 for use in a motor vehicle according to an embodiment described herein. Directional references such as top, bottom, upper, lower, upward, downward, longitudinal direction, width direction, left side, right side, etc., used or shown in the specification, drawings, or claims are relative terms used for ease of description and are not intended to limit the scope of the invention in any way. Referring to the drawings, similar numbers in various views indicate similar or corresponding components.

[0033] like Figure 1 As depicted, the seat assembly 10 includes a seat back 12 pivotally connected to the seat cushion 14 via inner and outer reclining assemblies 16. The reclining assemblies 16 are configured to prevent rotation of the seat back 12 relative to the seat cushion 14 when locked. The reclining assemblies 16 are selectively unlocked by actuating a release lever 18 operatively connected to the respective reclining assembly 16.

[0034] The seat assembly 10 includes a remote handle assembly 20 configured to actuate a release lever 18 to remotely unlock the recliner assembly 16. A first embodiment of the remote handle assembly 20 is described in... Figures 2 to 16 As shown in the figure, the remote handle assembly 20 includes a handle spline 22, a pulley 24, and a handle bracket 26. The pulley 24 is pivotally connected to both the handle spline 22 and the handle bracket 26.

[0035] Reference Figures 2 to 6 The handle spline 22 includes a generally cylindrical segment 28 having an external spline 30 and a longitudinally extending passage 32 through the cylindrical segment 28. For example... Figure 6 The depicted passage 32 has a butterfly-shaped cross-section with opposite side portions 34 and 36. (As shown...) Figure 5 and Figure 6 As shown, edge 38 extends circumferentially around the proximal end of the cylindrical section 28 of the handle spline 22, thereby forming a cavity 40. Figure 6As depicted, the spring groove 42 extends radially through the edge 38, and the actuator protrusion 44 projects radially from the edge 38. The actuator protrusion 44 includes a cam surface 46, the purpose of which is further described below. In one embodiment, as a non-limiting example, the handle spline 22 is formed of a zinc alloy such as zinc alloy 5 (ASTM AC41A).

[0036] Reference Figures 2 to 5 The pulley 24 includes a hub 48 and a sector 50 projecting radially from the hub 48. A pivot hole 52 extends axially through the hub 48 and defines the axis of rotation of the pulley 24. Opposite main cable channels 54 extend circumferentially along the outer portion of the sector 50 and terminate in retaining holes 56 that extend axially through the sector 50. Passages 58 extend between each cable channel 54 and each retaining hole 56. As best shown in FIG13, secondary cable channels 60 extend circumferentially along the outer portion of the sector 50 and terminate in an end wall 62 having cable holes 64 extending circumferentially through the end wall 62. Figure 3 As depicted, pulley 24 includes a boss 66 projecting from the distal surface 68 of pulley 24. Boss 66 is configured to frictionally engage with a cam surface 46 on actuator protrusion 44, such as... Figure 4 As shown. In one embodiment, as a non-limiting example, pulley 24 is formed of plastic such as nylon 6 / 6.

[0037] Reference Figure 3 The handle support 26 includes a keyhole 70, a spring hole 72, and opposing attachment slots 74, 76 extending laterally through the handle support 26. Figure 3 In the illustrated embodiment, the keyhole 70 has a double-d shape. As a non-limiting example, the handle support 26 is formed of steel.

[0038] Reference Figure 5 and Figure 7 The remote handle assembly 20 also includes a pin 78 configured to hold the components of the remote handle assembly 20 together. The pin 78 includes a central segment 80 extending from the head 82. Figure 6 As shown, the central section 80 has a double-d cross-section, wherein generally parallel sidewalls 84 extend between curved end walls 86. The central section 80 is sized and shaped such that it passes through and is pivotally connected to the passage 32 in the handle spline 22, while the head 82 is sized and shaped such that it does not pass through the passage 32 in the handle spline 22. Figure 7 As shown, the protrusion 88 on the proximal end of the head 82 extends radially from the central segment 80.

[0039] like Figure 7As shown, a generally cylindrical section 90 protrudes axially from the central section 80 away from the pin 78. The cylindrical section 90 is sized and shaped such that it passes through and is pivotally connected to the pivot hole 52 in the hub 48 of the pulley 24. A stop boss 92 on the proximal end of the central section 80 extends radially from the cylindrical section 90. An end section 94 protrudes axially from the cylindrical section 90 and forms the proximal end of the pin 78. A base boss 96 on the proximal end of the cylindrical section 90 protrudes radially from the end section 94.

[0040] like Figure 9 As shown, the end segment 94 of pin 78 and the keyhole 70 in handle bracket 26 are sized and shaped such that the end segment 94 passes through the keyhole 70 in handle bracket 26, but does not rotate within the keyhole 70. Figure 9 In the exemplary embodiment shown, as a non-limiting example, the end segment 94 of the pin 78 and the keyhole 70 in the handle bracket 26 have a double-d shape. As a non-limiting example, the pin 78 is formed of carbon steel such as SAE J403 grade 1018.

[0041] like Figure 12 As best shown, the remote handle assembly 20 also includes a pulley spring 98, such as a torsion spring or a coil spring. The pulley spring 98 is operatively connected between the pulley 24 and the handle support 26, and applies a biasing force to the pulley 24, thereby causing the pulley 24 to move along… Figure 2 The rotation is shown in a clockwise direction (arrow 102). As a non-limiting example, the pulley spring 98 is formed of music wire, such as ASTM A228.

[0042] Reference Figure 3 and Figure 10 The remote handle assembly 20 also includes a spline spring 104, such as a coil spring, torsion spring, etc. In one embodiment, as a non-limiting example, the spline spring 104 is formed of a musical wire such as ASTM A228. The spline spring 104 is operatively coupled between the handle spline 22 and the pin 78, wherein the spline spring 104 applies a biasing force to the handle spline 22, thereby causing the handle spline 22 to move along... Figure 2 Rotate clockwise as shown (arrow 102). It will be understood that the spring geometry of the spline spring 104 and pulley spring 98 can be adjusted to meet the torque requirements of different seat components 10.

[0043] like Figure 3 and Figure 4The depicted remote handle assembly 20 also includes a manual cable attachment 106 and a power cable attachment 108. The manual cable attachment 106 and the power cable attachment 108 have respective base portions 110, 112 configured to securely attach the cable attachments 106, 108 to corresponding attachment slots 74, 76 in the handle holder 26. The manual cable attachment 106 includes a pair of holes 114, and the power cable attachment 108 includes a cable hole 116. In one exemplary embodiment, as a non-limiting example, the manual cable attachment 106 and the power cable attachment 108 are formed of a plastic such as nylon 6 / 6.

[0044] Figure 11 to Figure 16 The illustration shows an assembly method of a remote handle assembly 20 according to an embodiment of the present invention. Referring to FIG11, the handle spline 22 is slid onto the pin 78 (arrow 118) until the distal end of the handle spline 22 abuts the boss 88 on the head 82 of the pin 78. Next, the spline spring 104 is inserted into the cavity 40 in the handle spline 22 (arrow 120), wherein the inner end 122 of the spline spring 104 is wound around the central section 80 of the pin 78, and the outer end 124 of the spline spring 104 passes through the spring groove 42 in the handle spline 22, as shown. Figure 10 As shown. Referring back to Figure 11, next, pulley 24 slides onto pin 78 (arrow 126) through pivot hole 52 until the stop boss 92 on pin 78 abuts the distal surface 128 of hub 48 of pulley 24, as shown. Figure 5 As shown. At this point, the edge 38 of the handle spline 22 is adjacent to the distal surface 128 of the hub 48 of the pulley 24.

[0045] Next, assemble pulley spring 98 onto pulley 24 (arrow 130). For example... Figure 12 As shown, the second end 132 of the pulley spring 98 frictionally engages with the side portion 134 of the pulley 24, and the first end 136 of the pulley spring 98 is inserted through the spring hole 72 (arrow 138) in the handle bracket 26. As shown by arrow 140, the end portion 94 of the pin 78 is then aligned with the key hole 70 in the handle bracket 26 and inserted into the key hole 70 in the handle bracket 26, such that the base boss 96 on the pin 78 frictionally engages with the distal surface 142 of the handle bracket 26, as shown. Figure 5 What is depicted.

[0046] Figure 13 shows the end portion 94 of the pin 78 protruding from the rear side of the handle bracket 26. Next, the end portion 94 of the pin 78 is riveted flush with the handle bracket 26, as shown by element 94S in Figure 14. Alternatively, the end portion 94 can be studded against the handle bracket 26. The pin 78 after the riveting process is shown in Figure 15, and the pin 78 is removed from the remote handle assembly 20. (Refer to...) Figure 5 As shown in Figure 15, the lateral loosening of the handle spline 22 is controlled by the protrusions 88, 92, and 96 on the pin 78 that define the internal hard stop during the riveting or studding process. Figure 16 As depicted, after the pin 78 is riveted or staked against the handle bracket 26, the base portion 110 of the manual cable attachment 106 and the base portion 112 of the electric cable attachment 108 are fixedly connected to the corresponding attachment slots 74, 76 (arrows 144, 146) in the handle bracket 26.

[0047] Reference Figure 1 The main Bowden cables 148, 148' operatively connect the remote handle assembly 20 to the corresponding release lever 18. The proximal ends of the main Bowden cables 148, 148' are inserted through the corresponding cable holes 114 in the manual cable attachment 106 and extend through the corresponding cable channels 54 and passages 58 in the pulley 24, terminating in the retaining hole 56. Figure 4 As best shown in the diagram, each main Bowden cable 148, 148' extends longitudinally through a conduit 150, which has a distal end fixedly connected to the seat assembly 10 via an assembly attachment 152 and a proximal end fixedly connected to a manual cable attachment 106.

[0048] The seat assembly 10 also includes an electric actuator 154 operatively coupled to the remote handle assembly 20 via a secondary Bowden cable 156. When the electric actuator 154 is actuated, it applies tension to the secondary Bowden cable 156. When the electric actuator 154 is deactivated, the tension is removed from the secondary Bowden cable 156.

[0049] The proximal end 158 of the secondary Bowden cable 156 is inserted through the cable hole 64 in the secondary cable channel 60 and pulley 24 into the cable hole 116 in the motor cable attachment 108 and terminates at the end fitting 160. The secondary Bowden cable 156 extends longitudinally through the secondary conduit 162, which is fixedly connected to the motor cable attachment 108.

[0050] like Figure 1As illustrated, the seat assembly 10 also includes a recliner handle 164, which is positioned for easy access by an occupant and operatively connected to the remote handle assembly 20. The recliner handle 164 is rotatable between an unactuated position (illustrated as recliner handle 164) and an actuated position (illustrated as recliner handle 164'). The recliner handle 164 is spring-biased toward the unactuated position.

[0051] The recliner handle 164 has an internal spline configured to engage in a mating manner with the external spline 30 on the handle spline 22. For example... Figure 6 As depicted, the opposite side portions 34 and 36 of the passage 32 in the handle spline 22 define the unacted and actuated positions of both the handle spline 22 and the recliner handle 164. The side portions 34 and 36 of the passage 32 can be adjusted for the specific travel range required by the recliner handle 164.

[0052] To unlock the recliner assembly 16, the occupant rotates the recliner handle 164 around the pin 78 from the unacted position to the... Figure 1 The actuation position is shown for element 164'. Rotating the tilting lever handle 164 to the actuation position 164' will cause the actuator protrusion 44 of the handle spline 22 to surround the pin 78 along... Figure 2 The actuator protrusion 44 rotates counterclockwise (arrow 102') to the actuated position (as shown by actuator protrusion 44'). The engagement between the cam surface 46 of actuator protrusion 44 and the boss 66 on pulley 24 causes pulley 24 to rotate counterclockwise (arrow 102') around pin 78 to the actuated position (as shown by actuator protrusion 44'). Figure 2 (As shown in sector 50'). Rotating sector 50 to sector actuation position 50' applies tension to main Bowden cables 148, 148', which actuates release lever 18 to unlock recliner assembly 16. When the occupant holds recliner handle 164 in actuation position 164' and recliner assembly 16 is unlocked, the occupant can pivot seat back 12 relative to seat cushion 14.

[0053] After the occupant releases the reclining handle 164, the spline spring 104 causes the actuator protrusion 44 of the handle spline 22 to move around the pin 78 along... Figure 2The clockwise rotation (arrow 102) from the actuated position 44' to the deacted position 44 returns the recliner handle 164 to the deacted position. Additionally, the pulley spring 98 causes the sector 50 to rotate clockwise (arrow 102) around the pin 78 from the actuated position 50' to the deacted position 50, because the load applied to the pulley 24 by the actuator protrusion 44 has been removed. When the sector 50 returns to the deacted position 50, tension is removed from the main Bowden cables 148, 148', which removes the tension applied to the release lever 18, causing the recliner assembly 16 to automatically relock.

[0054] Reference Figure 1 and Figure 2 When the occupant initiates the fold-flat function, the electric actuator 154 applies tension to the secondary Bowden cable 156, causing the sector 50 to rotate counterclockwise (arrow 102') around the pin 78 to the sector actuation position 50'. The rotation of the sector 50 to the sector actuation position 50' applies tension to the main Bowden cables 148, 148', thereby actuating the release lever 18 and causing the recliner assembly 16 to unlock. At this point, the seat back 12 can rotate so that it covers the seat cushion 14. During the fold-flat function, the recliner handle 164 disengages from the electric actuator 154, keeping the recliner handle 164 stationary while the electric actuator 154 rotates the sector 50. In order to relock the recliner assembly 16, the electric actuator 154 removes tension from the secondary Bowden cable 156, which allows the pulley spring 98 to rotate the sector 50 around the pin 78 in a clockwise direction (arrow 102) toward the sector's unactuated position 50.

[0055] The second embodiment of the remote controller assembly 20' is as follows Figure 17 and Figure 18 As shown, similar reference numerals with suffixes denote elements similar to those described above. Only the significant differences between the two embodiments are reflected in the figures and the following description. In a second embodiment of the remote handle assembly 20', pin 78' is fixedly connected to handle bracket 26' by bolt 166. A threaded shaft 168 on bolt 166 extends from bolt head 170 and is configured to engage with an axially extending threaded hole 172 in the proximal end of pin 78'. Figure 18 As shown, the remote handle assembly 20' is fully assembled, wherein the bolt head 170 is adjacent to the rear side of the handle bracket 26'.

[0056] The third embodiment of the remote controller assembly 20 is as follows: Figures 19 to 21As shown, similar reference numerals with double suffixes denote elements similar to those described above. Only significant differences between embodiments are reflected in the figures and the following description. In the third embodiment, pin 78” is inserted through keyhole 70” in handle bracket 26” and fastened to handle spline 22 by bolt 174.

[0057] Reference Figure 19 The pin 78” has a key shaft 176 projecting from a stepped flange 178. The stepped flange 178 includes a first boss 180 offset from a second boss 182. The key shaft 176 has a double-d cross-section. The keyhole 70” in the handle bracket 26” is sized and shaped such that the second boss 182 will enter the keyhole 70”. A threaded hole 184 extends axially into the distal end of the pin 78”. The threaded shaft 186 on the bolt 174 extends from the bolt head 190 and is configured to engage in a mating manner with the threaded hole 184 in the pin 78”.

[0058] The remote handle assembly 20” is assembled by inserting the distal end of pin 78” into the keyhole 70” in the rear part of the handle bracket 26”. Next, the components of the remote handle assembly 20” are installed onto pin 78” in reverse order, and the threaded shaft 186 of bolt 174 is inserted into the passage 32 in the distal end of the handle spline 22 and into the threaded hole 184 in pin 78”. The fully assembled remote handle assembly 20” is as follows. Figure 20 and Figure 21 As shown.

[0059] As described above, the seat assembly 10 of the present invention includes remote handle assemblies 20, 20', and 20"; the remote handle assemblies 20, 20', and 20" include pins 78, 78', and 78"; these pins 78, 78', and 78" axially pass through the handle spline 22 and are fixedly connected to the handle brackets 26, 26', and 26"; the stepped pins 78, 78', and 78" have internal hard stops 88, 92, and 96 that control the lateral loosening of the handle spline 22. Furthermore, the remote handle assemblies 20, 20', and 20" lack a housing, a cover, and fasteners that securely connect the cover to the housing. The reduction in the number of components in the remote handle assemblies 20, 20', and 20" reduces component costs and manufacturing complexity.

[0060] The invention has been described in an illustrative manner, and it should be understood that the terminology used is intended to be descriptive rather than limiting. Many modifications and variations of the invention are possible based on the foregoing teachings. Therefore, it should be understood that the invention can be practiced in ways other than those specifically described within the scope of the appended claims.
