The specific embodiment

Foldable chair support shown in Fig. 4,5 also is its bracing frame 2 of being made up of eight support bars 21,

The two ends of each support bar 21 are articulated in twos mutually by the articulated

part

3,4 that connects two " L " shape respectively.

Wherein there is the end 211 of two support bars 21 to be articulated in the middle part 212 of two support bars 21 in addition respectively, like this, there are four strong points the below of this leisure chaise longue, but there are five strong points in the top, one of them strong point C is as backrest, other is two strong point D, E is as handrail, two lower strong point F, G is as an end of seat support, in order to strengthen intensity, at two strong point F, articulate a bracing piece 6 between two support bars 21 of G formation seat support one end, bracing piece 6 is again by two motion bars that are articulated 61,62 form, and a motion bar 61 is provided with spacing barricade 611 therein, to limit two motion bars 61, the activity space that has only 180 degree between 62.

Key of the present utility model is: add a movable cross bar 7 at the strong point C place that forms backrest, the two ends of this cross bar 7 are by two " 7 " shape connectors 8 cross bar 7 to be connected between two support bars 21, and wherein a connection piece 8 is rivet clasp ends in a support bar 21; Another connector 8 is ends that movable sleeve is fixed in another support bar 21.

And on two fulcrum F, G forming seat support, 212 backs, two support bar 21 middle parts are provided with extension 211 so that be nested with chair cloth 1 on this fulcrum F, G being articulated in addition in the end of two support bars 21.

After launching this bracing frame, chair cloth 1 can be placed on the movable cross bar 7 of back support point and each fulcrum D, E and two extensions 211 and just form a leisure chaise longue.
