Abstract
An attachment mechanism may include an assembly having an engagement member moveable between retracted and extended positions, a latch member movable between latched and unlatched positions, and a fastener member moveable between unlock and lock positions. The mechanism may include a housing configured to receive the assembly and having a receptacle formed therein to receive the engagement member in the extended position. During insertion of the assembly in the housing, the latch member may be configured to automatically move from the latched to the unlatched position and the engagement member may be configured to automatically move from the retracted to the extended position into the receptacle. In response to movement of the latch member to the unlatched position, the fastener member may be configured to automatically move from the unlock to the lock position to lock the engagement member in the extended position for attachment of the assembly and housing.

DETAILED DESCRIPTION
[0013] As required, detailed non-limiting embodiments are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary and may take various and alternative forms. The figures are not necessarily to scale, and features may be exaggerated or minimized to show details of particular components, elements, features, items, members, parts, portions, or the like. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art.
[0014] With reference to the Figures, a more detailed description of non-limiting exemplary embodiments of an attachment mechanism and a method for attaching modules with such an attachment mechanism will be provided. For ease of illustration and to facilitate understanding, like reference numerals may be used herein for like components and features throughout the drawings.
[0015] As previously described, modularity is under consideration in the automotive industry as one path to contain and/or reduce the cost of assembly in just-in-time (JIT) manufacturing. Current assembly techniques employ conventional fastening methods using, for example, bolts and/or welding. In one form, however, modularity may require assembly of modules without access to or use of such conventional fastening methods, i.e., “blind” assembly. Nevertheless, in modularity involving blind assembly, serviceability of the modules involved and/or their components is still needed.
[0016] As a result, as also previously described, there exists a need for an attachment mechanism and a method using such an attachment mechanism that would facilitate modularity involving blind assembly or attachment of modules to reduce manufacturing costs, yet still allow or enable serviceability of such modules and/or their components. In that regard, members or carriers of such an attachment mechanism would engage with a module to provide a physical interface or a mechanical or structural connection in order to transfer load. Members or carriers of such an attachment mechanism may also establish, complete, or provide an electrical connection as the modules engage, which electrical connection may enable, allow, or provide for electrical power transfer or control signal or data communications.
[0017] In that regard,
[0018] The assembly 12 may include one or more engagement members 16a, 16b moveable between a retracted position (
[0019] As also seen in
[0020] In that regard, latch member 18 may be provided or configured to cooperate with a spring 26, which may be a coil spring. The spring 26 may be configured to bias the latch member 18 toward the latched position. Similarly, each engagement member 16a, 16b may be provided or configured to cooperate with a spring 28a, 28b, which also may be a coil spring. Each spring 28a, 28b may be configured to bias the associated engagement member 16a, 16b toward the extended position.
[0021] Moreover, the housing 14 may be configured to contact the latch member 18 during insertion (see arrow A) of the assembly 12 into the housing 14. As seen in
[0022] As a result, during insertion of the assembly 12 into the housing 14, the latch member 18 may contact the surface 30 of the housing 14, which contact may actuate or automatically move the latch member 18 (against the force of the spring 26, which is compressed as a result) from the latched position (
[0023] Still referring to
[0024] In that regard, it should be noted that assembly 12 (including receptacle 34), housing 14 (including receptacles 24a, 24b, surface 30, and tab 32), engagement members 16a, 16b (including receptacle 22a, 22b), latch member 18 (including projections 20a, 20b), spring 26, and springs 28a, 28b may comprise electrically conductive or electrically insulative materials having appropriate density, gauge, tensile strength, and/or other physical properties to enable, provide, and/or accomplish the mechanical and/or electrical functions described herein. It should also be noted that the assembly 12 and the housing 14 may be integrated with, incorporated in, or attached to respective modules and/or components to thereby provide for mechanical and/or electrical attachment of such modules and/or components. In that regard, such modules and/or components may comprise, as an example only, members or portions of a vehicle seat back frame. In such an example, the assembly 12 may be integrated with, incorporated in, or attached to one frame member, such as a side frame member, and the housing 14 may be integrated with, incorporated in, or attached to another frame member, such as a top frame member, in order to accomplish mechanical and/or electrical attachment of the vehicle seat side frame member to the vehicle seat top frame member by attachment of the assembly 12 and the housing 14 as described herein. As those of ordinary skill will understand, the locations of the assembly 12 and the housing 14 could be reversed in another example between the side frame member and the top frame member.

That is, one or more of the engagement pins 16a′, 16b′ may comprise an electrically conductive material or include an electrically conductive portion which, when the engagement pin 16a′, 16b′ is in the extended position in the associated receptacle 24a′, 24b′ of the housing 14′ and the assembly 12′ is attached to the housing 14′, may establish, complete, or provide an electrical connection within a module or component associated with the assembly 12′ or the housing 14′, or between a module or component associated with the assembly 12′ and a module or component associated with the housing 14′. In that regard, the module or component associated with the housing 14′ and the receptacles 24a′, 24b′ thereof may likewise comprise an electrically conductive material or include an electrically conductive portion to facilitate such an electrical connection.
[0039] Referring still to
[0040] The method may further comprise, in response to movement of the latch member 18′ to the unlatched position, automatically moving the fastener member 40 from the unlock position to the lock position to lock the engagement member 16a′, 16b′ in the extended position for attachment of the assembly 12′ to the housing 14′. The method may also comprise manually moving the fastener member 40 from the lock position to the unlock position, and, in response to movement of the fastener member 40 from the lock position to the unlock position, moving the engagement member 16a′, 16a″, 16b′, 16b″ from the extended position to the retracted position for detachment of the assembly 12′ from the housing 14′.
