Chair and/or bed arrangement
First Claim
1. A chair and/or bed arrangement comprising a base, at least one sitting and/or lying member, which is pivotable about a horizontal axis by means of at least one first pivot arm, at least one first power exerting device for actuating said first pivot arm, a container generally closed at all sides, said first power exerting device being housed within said container, said container being supported relative to the base by means of a supporting device, said first pivot arm having a pivot shaft extending into the interior of the container, the supporting device comprising at least one second pivot arm which is similar to said first pivot arm and having a pivot shaft extending into the interior of the container through a wall portion thereof, a second power exerting device for actuating the second pivot arm being also housing within said container the container constituting a supporting connection between the first and second pivot arms and serving as a transmitter of support forces between the sitting and/or lying member and the base, the container having the character of a box girder having top, bottom and side walls, said girder being longitudinally elongated and having a substantially smaller width than the sitting and/or lying member, and the pivot shafts for the first and second pivot arms penetrating through the side walls of the girder.

Abstract
A bed comprises a base (1), a frame (2), which is vertically adjustable relative to the base by means of pivot arms (3), lying members (7-9), which are adjustable relative to the frame (2) by means of second pivot arms (12, 13) and power devices on the frame for causing the pivot arms to move. The frame (2) is designed as a container generally closed at all sides, said power devices being enclosed within said container, the pivot shafts of the pivot arms extending into the interior of the container through wall portions thereof. (FIG. 2).

10. A chair and/or bed arrangement comprising a base, at least one sitting and/or lying member, which is pivotable about a horizontal axis by means of at least one first pivot arm, at least one first power exerting device for actuating said first pivot arm, a container generally closed at all sides, said first power exerting device being housed within said container, said container being supported relative to the base by means of a supporting device, said first pivot arm having a pivot shaft extending into the interior of the container, the supporting device comprising at least one second pivot arm which is similar to said first pivot arm and having a pivot shaft extending into the interior of the container through a wall portion thereof, a second power exerting device for actuating the second pivot arm being also housed within said container, the container constituting a supporting connection between the first and second pivot arms and serving as a transmitter of support forces between the sitting and/or lying member and the base, said sitting and/or lying member including a back member, a seat member and a leg member, means hingedly connecting said seat member to said back member and said leg member, there are being two of the first pivot arms for pivoting the back member and the leg member in the vertical plane, a frame including a support member for cooperating with the leg member to form a pivot point therefor, said pivot point being located between on one hand the hinge connection between the leg member and the seat member and on the other hand the hinge connection between the leg member and the first pivot arm associated with the back member, and the support member being arranged on a vertically pivotable link for supporting the leg member and seat member so that they form a generally planar surface or otherwise assume a predetermined mutual angular relation when the vertically pivotable link and the leg member are pivoted upwardly by means of the first pivot arm associated with the leg member.
