Patent number: 6986542Abstract: A retractable seat to be attached to a floor may include a seat cushion, a seat back rotatably supported on the seat cushion, and a link mechanism for supporting the seat cushion on the floor. The link mechanism includes a front leg and a rear leg that are pivotally connected to the seat cushion and the floor so that the seat can be switched between a use condition and a retracted condition. The front and rear legs respectively have a different link length so as to produce a difference between a rotating range of the front leg and a rotating range of the rear leg. The seat may further include a compensation mechanism for compensating for the difference between the rotating ranges of the front and rear legs within an operating range of the link mechanism.Type: GrantFiled: February 25, 2004Date of Patent: January 17, 2006Assignee: Araco Kabushiki KaishaInventors: Taku Imajo, Makoto Sakai

Patent number: 6966598Abstract: The present invention concerns an apparatus for adjusting the vertical and longitudinal position and the inclination of a pivotable seat part (2) of a vehicle seat (1) relative to a floor structure (4) of the vehicle, having a linkage that encompasses a linkage part, constituted by at least one articulated rectangle (ABCD), that has a base (AB), two rockers (BC, AD), and a coupler (CD). The base (B)is arranged in a plane extending substantially parallel to a longitudinal seat axis (X—X).The rockers (BC, AD)are pivotable about rotation axes extending substantially parallel to transverse seat axis. The linkage encompasses two linkage parts, each constituted by at least one articulated rectangle (ABCD;CDEF), that each have a base (AB,CD), two rockers (BC,AD;DE,CF),and a coupler (DC,EF).Type: GrantFiled: August 23, 2001Date of Patent: November 22, 2005Assignee: Johnson Controls Technology CompanyInventor: Uwe Schmale

Patent number: 6916057Abstract: A folding vehicle passenger seat for agricultural or industrial utility vehicles, includes a seat member which can be pivoted from a seated position to a position folded upward. A sliding bearing mechanism is coupled to the rear portion of the seat member so that the seat member can be guided in a sliding motion and so that the seat member can pivot about an axis. When the seat member is folded upward the sliding bearing mechanism slides downward from an upper position along the guide and simultaneously rotates relative to the guide.Type: GrantFiled: February 18, 2004Date of Patent: July 12, 2005Assignee: Deere & CompanyInventor: Michael Teich

Patent number: 6817645Abstract: A seat arrangement for a vehicle includes a first row of seats, a second row of seats mounted behind the first row of seats in a vehicular cabin, and a third row of seats mounted behind the second row of seats in the cabin. A second row seat is slidable in the longitudinal direction, and a seat cushion of the third row seat can be pivoted about a pivotal axis in the vicinity of its front edge into the upright position. When the seat cushion of the third row seat is in the upright position and the second row seat is slid rearwardly, the seat cushion of the third row seat and the second row seat are positioned closely with each other. The second row seat can slide rearwardly without interference from the step on the floor or rear wheel housings bulging out into a cabin.Type: GrantFiled: March 14, 2003Date of Patent: November 16, 2004Assignee: Mazda Motor CorporationInventors: Tomoo Taguchi, Keiichiro Shibata

Patent number: 6637819Abstract: A seat assembly for an automotive vehicle comprising a main support frame adapted to secure the seat assembly to the floor of the vehicle. A seat cushion is rotatably journaled to the main support frame for rotation between a seating position and a fold flat position rotated generally 180 degrees about the frame. A seat back is pivotally coupled to the main support frame for rotation between a generally upright seating position to a fold flat position aligned generally flush with the seat cushion in the fold flat position. A lower track is fixedly secured to the main support frame and an upper track is fixedly secured to the seat back and slidably secured to the lower track. An automatic fold mechanism is operatively coupled between the upper track and the seat cushion for automatically rotating the seat cushion between the seating position and the fold flat position in response to fore and aft sliding movement of the upper track along the lower track.Type: GrantFiled: December 11, 2001Date of Patent: October 28, 2003Assignee: Intier Automotive Inc.Inventor: Omar D. Tame
