Patent number: 4858459Abstract: An inertia force balancing apparatus for a machine haivng a reciprocating heavy object, such as a Pilger rolling mill provided with a heavy object stand having a pair of Pilger mill rolls and horizontally supported such as to be reciprocable and with a drive device for imparting reciprocating motion to the Pilger mill stand by a motive power converted from rotational motion, into reciprocating motion. A spring device secured at its end to the heavy object and adapted to balance the inertial force of the reciprocating motion of the heavy object. A control device is provided for changing the spring force of the spring device in accordance with the rotational speed of the rotational motion of the drive device.Type: GrantFiled: July 29, 1987Date of Patent: August 22, 1989Assignee: Sumitomo Heavy Industries, Ltd.Inventor: Muneharu Takahashi

Patent number: 4682763Abstract: An adjustable cushion support device for adjusting the holding pressure applied to support a seat cushion. The adjustable support device includes a frame member having a first end and a second end to support the cushion. A spring member is mounted on the frame member between the first end and the second end for flexibly supporting a load. A control mechanism is mounted on the frame member and is connected to the spring member for adjusting the holding pressure applied to the spring member. The control mechanism includes an enforcing member pivotally supported on the frame member for pushing the spring member upwards, a biasing member for biasing the enforcement member, and an operating lever to control the inclination of the biasing member to regulate the holding pressure applied to the spring member.Type: GrantFiled: March 25, 1985Date of Patent: July 28, 1987Assignee: Aisin Seiki Kabushiki KaishaInventors: Kenichi Kazaoka, Hiroshi Okazaki, Yasuhisa Inaba

Patent number: 4671569Abstract: A resilient back-up mechanism for a seat back structure of a vehicle seat for supporting a waist portion of a passenger sitting on the seat. An adjusting member is mounted on a seat back frame for pivotal movement and back-up means is also pivotably mounted on the seat back frame. An adjustable spring having one end engaged with the adjusting member and the other end engaged with the back-up means applies a resilient support to the back-up means against rearward movement. The amount of resilient support may be adjusted by swingably moving the adjusting member by an actuating means.Type: GrantFiled: September 17, 1985Date of Patent: June 9, 1987Assignee: Aisin Seiki Kabushiki KaishaInventors: Kenichi Kazaoka, Hiroshi Okazaki

Patent number: 4588172Abstract: In order to soften or stiffen the support offered by an elastic sheet, and in particular a vehicle seat back, the device comprises a flat spring (1) which is at each of its ends connected to the sheet (38), and fixed to a case (2, 3) containing an inclined disc (10, 12). Two discs are fixed to a control rod (24) which is mounted in the frame (36) of the seat and, when this rod is rotated, they cause the cases to be pivoted symmetrically, so that the spring is extended and stiffens the sheet or is shortened and renders the seat more soft.Type: GrantFiled: March 25, 1985Date of Patent: May 13, 1986Assignee: Cycles PeugeotInventors: Francois Fourrey, Patrice Ciciliani

Patent number: 4547918Abstract: The present invention relates to a body supporting network suitable for use with a load supporting system. The network includes at least first and second pluralities of elongate support members securable with the system for supporting a load. The first and second support members respectively extend in first and second directions to provide potential load receiving intersections where the first support members cross the second support members. The network includes adjustment means to vary network pressure response at each intersection and to permit changes in network contour. The network includes interconnecting means for connecting the elongate members at the intersections to maintain network integrity when the network is subjected to the load.Type: GrantFiled: August 16, 1983Date of Patent: October 22, 1985Assignee: Ontario Crippled Children's CentreInventors: Frederick D. Ginpil, Morris Milner, John W. Senders

Patent number: 4162807Abstract: A vehicle seat of the type having a seat back with a plurality of transverse serpentine springs therein is provided with a regulating apparatus for adjusting the firmness of the lower most springs to adjust the firmness of the seat back in the lumbar region. A torsion spring is wrapped about a vertically extending post in the lower corner of the seat back with the ends thereof operatively engaged with a lumbar plate engaging the seat spring adjacent the lower center portion of the seat back and with an intermediate portion of the spring extending outwardly from the post in engagement with a rotatable cam having surfaces of different radii engagable with the intermediate portion of the spring to vary the force of the torsion spring on the seat spring.Type: GrantFiled: October 31, 1977Date of Patent: July 31, 1979Assignee: Aisin Seiki Kabushiki KaishaInventor: Noboru Yoshimura

Patent number: 4162063Abstract: The typical helical springs used to support the bed within the frame of a trampoline or the like are modified to incorporate adjustable hooks threadedly anchored within the springs at one end so that their overall length, and thus the tension on the bed, can be varied and overstretching accommodated. Two principal versions are disclosed, the more preferred one including an additional inner spring biasing the adjustable hook to a retracted position.Type: GrantFiled: January 15, 1976Date of Patent: July 24, 1979Assignee: Nissen CorporationInventors: George P. Nissen, Harlan J. Kelly

Patent number: 4111070Abstract: A spring resistance cartridge assembly for a valve actuator is disclosed which offers resistance to movement in either direction of an axial member extending therein. The cartridge assembly has a base plate securable to an axial member and an opposing fixed plate which is secured in a non-movable position. Between the base plate and the fixed plate are two compression plates having spring members trapped therebetween. Bolts and studs attach the compression plates one to each, the base plate and the fixed plate.Type: GrantFiled: April 4, 1977Date of Patent: September 5, 1978Assignee: Dresser Industries, Inc.Inventor: Andrew Stratienko
