DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an arrangement in a foot rest, especially a foot rest associated with a passenger chair, said foot rest comprising in relation to the chair seat an inner supporting member serving to support the rear side of the leg, as well as an outer supporting member for placing the feet thereon, said supporting members being linked together for thereby allowing for a folded position when not being used and an unfolded position when in use, respectively.
PRIOR ART
From U.S. Pat. No. 2,044,992 there is known a customer chair comprising a double set of foot rests, the lower foot rest being used for adult users, whereas the upper foot rest is to be used for children. The foot rest itself comprises a rigid frame depending from the chair seat under a fixed angle, whereas the two foot rests can be pivoted between a substantial vertical position when not in use and a horizontal position for supporting the feet of an adult person or the feet of a child, respectively.
Such a prior art foot rest does not render the possibility of combining the support of a user's legs and feet, let alone the possibility of pivoting the complete foot rest to a substantially horizontal position for thereby constituting an extended lying support for the user of the chair, especially when the back rest of the chair has been reclined to a lying position.
From U.S. Pat. No. 2,174,622 there is known a passenger chair for aircrafts, especially a reclinable chair, comprising a combined leg and foot rest. The leg and foot rest is composed of two sections, namely a leg section and a foot section mutually connected by means of a hinge in such a manner that the foot section can be folded below the leg section, which is impractical in connection with the stowing away or the pulling forth of the combined leg and foot rest. In a special embodiment of the prior art leg and foot rest, the foot rest comprises a bracket which is slidably attached to the foot section and extends along the lower portion of the foot section for constituting a transverse bar onto which the feet or the heels can be rested. Such a slidable heel support further complicates the prior art leg and foot rest, since the adjustment of this heel bar must be effected by means of a complicated locking mechanism. Neither does this prior art leg and foot rest comprise means allowing for the mutually linked supporting members in a folded out user position to take various angular positions in relation to each other, in dependence of the angular position of for example the inner leg supporting member or section.
U.S. Pat. No. 2,935,123 relates to a leg support for an easy chair, said leg support comprising a plurality of regulating mechanisms comprising wing nuts and bolts. This prior art leg support is adapted to be mounted on the front side of an easy chair, and will consequently not be stowed away below the chair seat portion itself.
From U.S. Pat. No. 4,819,987 there is known a leg support for an aircraft seat, said leg support or foot rest comprising an outwardly extending leg supporting member which is pivotably connected to the seat frame, as well as a foot rest which is pivotably connected to the front end of the leg support. However, this prior art foot rest does not give any instructions for the two members to take different angular positions in relation to each other in an unfolded user position, let alone gives any instructions for at least one supporting member being provided with a foldable flap.
From CH 654 735 there is known a foot rest for an aircraft seat, comprising an inner leg supporting member and an outer foot supporting member which can be folded together in relation to each other in a stowed away position. However, neither does this foot rest give any instructions for two different members which are adapted to take different angular positions in relation to each other in an unfolded user position, let alone give instructions for at least one supporting member being provided with a foldable flap.
