Definitions

  • the present invention relates to reclining chairs, and in particular to an improved reclining chair of the'type including a movable back-rest, seat and leg-rest which are coordinated with each other to include at least two distinct phases of chair movement.
  • the well-known reclining chair comprises a support, a body-supporting unit including a back-rest and seat movably mounted on the support, a leg-rest mounted beneath the forward end of the seat and movable into various elevated leg-supporting positions, and appropriate linkage means coordinating the body-supporting unit and the leg-rest such that the leg-rest is elevated in response to the reclining movement of the chair.
  • Such chairs have been constructed either with a movable backrest and movable seat mounted on the support for reclining and inclining movement respectively or with a rigid seat and back-rest mounted on the support for movement as. a unit.
  • Ch-airs incorporating both a movable back-rest and movable seat are suitable for complete and full relaxation in that, in response to the reclining movement, the anglebetween the back-rest and seat is increased to comfortably accommodate the chair occupant in a stretched out or fully reclined attitude.
  • Chairs of. the type incorporating a rigid seat and back-rest which may be manufactured somewhat more cheaply, are suitable for accommodating the chair occupant in a tilted-back position, but in a sitting attiude, with the occupants legs supported on the elevated leg-rest. The consumer, in purchasing the reclining chair, is often required to make a choice between these two basic types of chairs, depending upon the consumers needs.
  • an object of the present invention to provide an improved reclining chair which exhibits the attributes of chairs of the type incorporating a body-supporting unit including a movable back-rest and movable seat and chairs of the type incorporating a body-supporting unit including a rigid back-rest and seat.
  • an improved reclining chair which is constructed to have a first movement phase from a sitting position to an intermediate tilted position during which there is substantially no relative angular displacement between the back-rest and seat, and a second movement phase from the intermediate tilted orsemi-reclined position to a fully reclined position during which the backrest is angularly displaced relative to the seat.
  • the functional attributes. of chairs incorporating body-supporting units having a movable seat and backrest or a body-supporting unit having a rigid 'seat and 2,948,331 Patented Aug. 9, 1960 back-rest may be realized.
  • the chair occupant may move to the intermediate or semi-reclined position wherein the body-supporting unit is tilted, with substantially no change in the angular displacement between the seat and back-rest and with the leg-rest elevated, which intermediate tilted or semi-reclined position is suitable for television viewing, sewing, reading, or the like.
  • the chair occupant may move the chair into various fully reclined positions wherein the angular relationship between the seat and back-rest is increased so that the chair occupant may be accommodated in a substantially stretched-out or fully reclined position, with the leg-rest remaining in an appropriate elevated position' supporting the legs.
  • my improved reclining chair of the double movement type comprises a support, a body-supporting unit including a back-rest and seat mounted on the support for reclining and inclining movement respectively, and means movably mounting the body-supporting unit on the support for a first movement phase from" a sitting position to an intermediate tilted or semi-reclined position during which there is substantially no relative angular displacement between the back-rest and seat and during which the leg-rest is elevated and for a second movement phase from the intermediate tilted or semireclined position to a fully reclined position during which the back-rest is angularly displaced relative to the seat, with the leg-rest remaining in a substantiallyelevated leg-supporting position.
  • the mounting means; for the body-supporting unit includes a carrier mounted on the support for turning movement, with means releasably engaging the carrier and holding the carrier against turning movement during the first phase or portion of the reclining movement.

  • Further leg-rest control means are operatively connected to the actuating member for elevating the leg-rest in re sponse to turning movement of the actuating member during the first phase of the reclining movement.
  • Appropriate means are interconnected between the carrier and the actuating member and are effective to dis.-' engage the means which releasably engage the carrier at the end of the first phase of the reclining movement such that during a further phase or portion of the reclining movement the carrier is movable and'is effective to incline the seat.
  • the arrangement issuch that the movement of the carrier, which in turn supports the actuating member during the second phase of the reclining movement, imparts the required inclination to the seat such that the desired angular relationship between the seat and back-rest is established during the second phase of the reclining movement, with the legrest being maintained in an elevated leg-supporting position.

Accordingly, in response to reclining movement of the back-rest 19, a rearwardly directed thrust is imparted via the driver link 24 to the actuating member 30 which turns the actuating member 30 about the pivotal mount 42.
  • this disengaging means takes the form of a coordinating link 96 having a pivotal connection 94 at one end to the carrier 44 and having a pin and slot interconnection 98, 99 at its other end to the actuating member 30. At the start of chair movement the pin 98 is intermediate the ends of the slot 99.
  • the pin 98 In response to the reclining movement of the chair, the pin 98 travels upward along the slot 99 through a lost motion stroke until such time as the pin 98' arrives at the upper end limit of the slot 99 (see Fig. 2). During the lost motion travel of the pin 98 of the coordinating link 96, the actuating member 30 is free to turn relative to the carrier 44. When the pin 98 arrives at the upper end of the slot 99 there is provided, at least momentarily, a binding connection between the carrier 44 and the actuating member 30.

  • This causes a rearwardly directed force to be applied to the driver link 24 which via its pivotal connection to the actuating member 30 causes the actuating member -30 to turn about its pivotal mount 42 on the carrier member 44.
  • This imparts an inclination to the seat such that the angle between the seat and back-rest does not substantially change as the chair moves into the intermediate tilted position and also elevates the leg-rest to the required leg-supporting position forwardly of the seat.
  • the pin 98 of the coordinating link 96 travels upwardly along the slot 99 as the actuating member 30 turns about the pivot 42.
