Tailgate support assembly with push-button release
A seating apparatus is provided including a seating member and a support mechanism. The seating member is pivotable between a first seating position and a second seating position. The support mechanism is attached to the seating member. The support mechanism is operable between a retracted position and an extended position. The support mechanism is adapted to engage a portion of a vehicle to support the seating member in the second seating position.
The present invention relates to a seat support mechanism and, more particularly, a seat support mechanism adapted for use with a rear or third row seat that is pivotable between a forward facing position and a rearward facing position.
BACKGROUND OF THE INVENTIONMinivan and sport utility markets are extremely competitive. A growing focus of the competition is the overall utility and comfort of these vehicles. One important utility feature that is gaining much attention includes flexible vehicle interiors and, more particularly, flexible rear or third row seating assemblies. Flexibility, in this sense, refers to the ability to modify the configuration of a particular seating assembly. For example, when attending an outdoor function, a consumer may desire to utilize the cargo compartment of the vehicle as a seating area. This would allow the consumer to sit within the vehicle while maintaining a direct line of sight with, and being able to hear, individuals outside of the vehicle. Thus, automobile manufacturers have developed a rear or third-row seat that is pivotable about the vehicle body from a forward seating position to a rearward seating position. A problem that exists, however, is that the cargo space of the vehicle is typically not configured to support the vehicle seat in this rear seating position.
SUMMARY OF THE INVENTIONA seating apparatus is provided including a seating member and a support mechanism. The seating member is pivotable between a first seating position and a second seating position. The support mechanism is attached to the seating member. The support mechanism is operable between a stored position and a supporting position. The support mechanism is adapted to engage a portion of a vehicle to support the seating member in the second seating position.
Another aspect of the present invention provides a vehicle seating apparatus including a seat and a support mechanism. The seat includes a first seating member and a second seating member. The seat is pivotable between a first seating position and a second seating position. The support mechanism is attached to the second seating member and is operable between a stored position and a supporting position. The support mechanism is adapted to engage a portion of a vehicle to support the seat in the second seating position.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
BRIEF DESCRIPTION OF THE DRAWINGSThe present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following description of the preferred embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The seating apparatus 10 generally includes a seat bottom 16, a seatback 18, a headrest 20, and a pivot mechanism 22. As shown in
The housing sleeve 24 generally includes an elongated tubular member having an external surface 32, an internal surface 34, a containing end 36, and a receiving end 38. A plurality of attachment flanges 40 append from the external surface 32 of the housing sleeve 24. The attachment flanges 40 are adapted to receive fasteners (not shown), such as screws, to fasten the support mechanism 12 to the seating apparatus 10. The internal surface 34 of the housing sleeve 24 defines an internal abutment collar 42 and a plurality of internal guide rails 44, as best seen in
The locking mechanism 28 includes a nut 58 and a biasing member 60. The nut 58 generally includes a cylindrical body defining a plurality of locking arms 62 and a blind bore 64. As best illustrated in
The support arm subassembly 30 is disposed within the housing sleeve 24 and includes a support arm 82 and a support arm sleeve 84. The support arm 82 is a generally elongated cylindrical member constructed of a rigid material such as steel. The support arm sleeve 84 is a generally tubular member receiving the support arm 82. The support arm sleeve 84 includes an external surface 86, an open end 88, and a closed end 90. The open end 88 includes a saw-toothed circumferential edge 92. The saw-toothed circumferential edge 92 includes a plurality of teeth 94. As best illustrated in
The external surface 86 of the support arm sleeve 84 defines a plurality of guide pads 102. The plurality of guide pads 102 extend radially outward from the external surface 86 of the support arm sleeve 84. The plurality of guide pads 102 each have a semi-circumferential dimension that is slightly smaller than the semi-circumferential dimensions of the blind guide slots 54 disposed between the internal guide rails 44 of the housing sleeve 24. This allows the guide pads 102 to freely slide within the blind guide slides 54 during actuation of the support mechanism 12. The plurality of guide pads 102 are disposed within the blind guide slots 54 to maintain the rotational disposition of the support arm subassembly 30 relative to the housing sleeve 24.
The following steps provide the transition between the above-described retracted and extended positions. With the support mechanism 12 in the retracted position, as illustrated in
Once this initial rotation is achieved, the force applied to the closed end 90 of the support arm subassembly 30 can be released. This enables the biasing member 60 to axially displace the nut 58 in the upward axial direction toward the support arm subassembly 30. Upon such axial displacement, the inclined unlocking surface 74 of the working edge 70 of the locking arm 62 of the nut 58 slidably engages the chamfered ends 48 of the internal guide rails 44 of the housing sleeve 24. This further causes the nut 58 to rotate in the clockwise direction, as viewed from the cap 26. This further rotation continues until the second longitudinal edge 68 of the locking arms 62 of the nut 58 passes the guide edge 52 of the guide rails 44 of the housing sleeve 24. At this point, the locking arms 62 of the nut 58 are substantially axially aligned with the plurality of blind guide slots 54 in the housing sleeve 24 disposed between the internal guide rails 44. The biasing member 60 is then enabled to fully extend and axially displace the nut 58 and support arm subassembly 30 to the extended position shown in
The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
