DETAILED DESCRIPTION

[0016] The following Detailed Description should be read with reference to the drawings, in which like elements in different drawings are identically numbered. The drawings, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of the invention. The Detailed Description illustrates by way of example, not by way of limitation, the principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention.

[0017] The present disclosure provides, in part, button assemblies for controlling seat positions, for use in, for example, airline seats. By way of example, airline seats may include positioning features for passenger comfort during travel. For example, seat backs may recline, foot rests may extend outward, lumbar supports may be provided, etc. Space around the button assembly may be limited, such as in a seat arm. This limitation in space makes it difficult to install a button assembly, particularly if the button assembly must be held from the underside for purposes of installation. Advantageously, the present disclosure provides button assemblies, such as snap-in button assemblies that are capable of being mounted on a seat panel, such as an armrest or a sidewall quickly and easily from the outside of the panel only. By contrast with conventional button assemblies, the button assemblies disclosed herein may be mounted onto the seat panel or armrest without having to hold the button assembly from the underside of the panel where space is limited. For example, the present button assemblies include one or more flexible retaining members which compress through a seat panel opening during installation and expand to a nominal position once the button assembly is advanced through the opening within the seat panel.

[0018] FIGS. 1A-1E depict a button assembly 100 in accordance with a first embodiment. With reference to FIG. 1A, the button assembly 100 is shown in a mounted position relative to a seat panel 140 (partially shown), the assembly 100 including an actuable button 105 which is used selectively by the occupant of the seat to control a position of the seat (not shown), as described in detail herein.

[0019] FIGS. 1B-1E provide various views of the button assembly 100, in accordance with FIG. 1A. The button assembly 100 according to this embodiment includes an actuable button 105, a button housing 125 and one or more flexible retaining members 120, as well as an outer cap or cover portion 110.

[0020] Further, the button assembly 100 according to this depicted embodiment includes a control cable activator 130 and a control cable holder 135, attached to a lower end of the button housing 125. When installed and as best shown in FIGS. 1C-1E, the control cable activator 130 includes a first engagement arm 131 that is initially disposed in relation to a lower shaft-like portion 106 of the actuable button 105 and a second engagement arm 132 having a through opening that supports a portion of a control cable 150, the latter being further housed within a control cable control sleeve 151. In operation, pressing the actuable button 105 will cause the lower portion 106 of the button 105 to contact the first engagement arm 131 of the control cable activator 130, the latter being pivotally attached by means of a pinned bracket 126 to the button housing 125 at a pivot point A. When engaged and according to this embodiment, the control cable activator 130 rotates clockwise, causing the supported control cable 150 to move from a first position to a second position (to the left as viewed in FIG. 1D and upward as shown in FIG. 1E). The control cable sleeve 151 is held in place, preferably by the control cable holder 135 during such movement.

[0021] FIG. 1E is a cross-sectional view of the button assembly 100 as mounted in an opening 145 in seat panel 140, in accordance with aspects set forth herein. According to this embodiment, a flexible retaining member 120 is provided on opposing lateral sides of the button housing 125, each flexible retaining member 120 being defined by a wedge shaped configuration including a cantilevered end that extends outwardly relative to the exterior surface of the button housing 125. When fabricated, the retaining members nominally assume a outwardly flexed position in which each member is configured to inwardly flex toward the outer surface of the button housing 125 when acted upon by a compressive force.

[0022] Upon insertion of the button assembly 100 into the seat panel 140 and when passing the edge of the opening 145, the inserted end of the one or more flexible retaining members 120 has a narrower width than the outer end, so that the members 120 may readily pass through the opening 145 and into the seat panel 140. As the button assembly 100 progresses into the opening 145, the one or more flexible retaining member 120 flex inward against the compressive force of the edges of the opening 145, allowing entry into the defined opening 145. Once the widest portion of the flexible retaining members 120 clears the opening 145, the flexible retaining members 120 are caused to bend outward, thereby returning the members to their original cantilevered shape and position due to the cessation of the compressive force. In the nominal seated position of the button assembly 100 within the seat panel 140 depicted in FIG. 1E, the cantilevered ends of flexible retaining members 120 are positioned opposite an inner surface 141 of the seat panel 140, and beyond the outer edge of the opening 145. This cantilevered positioning of the one of more flexible retaining members 120 against the inner surface 141 restricts removal of the button assembly 140 from the seat panel 140.

[0023] Still referring to FIG. 1E and when the button assembly 100 is seated, the outer cover or cap portion 110 of the button housing 125 defines a shoulder that covers an edge surface of the opening 145 in which the upper cover or cap portion 110 has an outer dimension (L.sub.1) relative to the width (L.sub.2) of the opening 145. In such a case, the upper cover or cap portion 110 of the button housing 125 is therefore positioned over the edge of the opening 145 and against the outer surface 142 of the seat panel 140. As previously noted, the number of flexible retaining members 120 may vary, depending on the mechanical strength desired, the materials employed, the dimensions of the parts, etc.

[0024] It will be understood that other configurations are possible. For example, FIG. 2 depicts a button assembly 200, in accordance with another embodiment. This assembly 200 includes a pair of flexible retaining members 220 that are defined by a first cantilevered portion 221 extending outwardly from an exterior lateral wall surface of the housing 125 at an acute angle and a second reflexed portion 222 that inwardly extends from the cantilevered portion 221 toward the bottom surface of a shoulder formed by the upper cover or cap portion 210 of the assembly 200. According to this specific embodiment, each of the retaining members 220 assumes a substantial “V-shape.” After insertion of the button assembly 200 into an opening defined in the seat panel (not shown in this view), the V-shaped retaining members 220 are caused to compress inwardly to permit assembly but in which the members are caused to expand outwardly and revert to their substantial “V-shape” once the members have cleared the opening into the seat panel. As in the prior described embodiment, the retaining members 220 prevent or inhibits removal of the seated assembly against the edges of the opening in the seat panel.

[0025] In operation, the cantilevered and reflexed portions 221, 222 are configured to move inwardly or compress upon insertion of the button assembly 200 into the opening in a seat panel (not shown) and then expand outwardly within the seat panel in the position shown in FIG. 2. Frictional forces between the edge of the opening in a seat panel and each retaining member 220 may further be increased by the addition of ribs 223, to further inhibit removal of the button assembly 200 after insertion into a seat panel.
