Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
An arrangement in seating furniture or seats for attaching flexible seat and back supporting elements, said furniture or seat including two frame or rail members forming opposite side portions of said seating furniture or seat, at least one recess in each of said frame or rail members, said recesses extending at least partially in the longitudinal direction of the said frame and rail members and opening into one of two opposite sides thereof, wherein a complementary ledge member is introducable into each of said recesses radially to the longitudinal axis thereof, a groove in said ledge member and extending in the longitudinal direction thereof in a plAne diverging outwardly from the middle plane of said seating furniture or seat, a side marginal portion of a flexible back and seat supporting material anchored in said groove and means to increase the spacing between said side portions to put the flexible seat and back supporting elements under tension after anchoring said marginal portions in said grooves.
Claim 2
Dependent Claim
164 words
An arrangement in seating furniture or seats for attaching flexible seat and back supporting elements, said furniture or seat including two frame or rail members forming opposite side portions of said seating furniture or seat, at least one recess in each of said frame or rail members, said recesses extending at least partially in the longitudinal direction of the said frame and rail members and opening into one of two opposite sides thereof, wherein a complementary ledge member is introducable into each of said recesses radially to the longitudinal axis thereof, a groove in said ledge member and extending in the longitudinal direction thereof in a plAne diverging outwardly from the middle plane of said seating furniture or seat, a side marginal portion of a flexible back and seat supporting material anchored in said groove and means to increase the spacing between said side portions to put the flexible seat and back supporting elements under tension after anchoring said marginal portions in said grooves.
Claim 3
Dependent Claim
45 words
An arrangement as claimed in claim 1, wherein the ledge and the recess have a cross-section of parallelogram shape, and wherein the side walls of the recess diverge outwardly in relation to the longitudinal middle plane of the piece of furniture and the seat, respectively.
Claim 4
Dependent Claim
14 words
An arrangement as claimed in claim 1, wherein the ledge consists of resilient material.
Claim 5
Dependent Claim
147 words
An arrangement as claimed in claim 1, including side members consisting of section rails or frames in which said recesses are provided in parallel with the longitudinal axis of the respective section and open into their upper or lower side, wherein the ledge is of U-shaped cross-section having its open side located in the opening of the recess and side members shaped in such a way that these will form between them a slot of uniform and relatively narrow width and extending from the open side over an essential part of the depth of the recess and being parallel with the longitudinal middle plane of the recess, said slot being adapted to receive said marginal portion and being widened at its inner end to form a space to receive a thickened margin of said marginal portion, said slot and space opening into the ends of the ledge.
Claim 6
Dependent Claim
26 words
An arrangement as claimed in claim 1, wherein the side walls of the slot are provided with flutes extending in the longitudinal direction of the rail.
Claim 7
Dependent Claim
65 words
An arrangement as claimed in claim 1, the sections being rigidly connected with each other through transverse elements of variable length, wherein there is provided in the cavity of the section rail a partition receiving the recess, and wherein said transverse element is introducible through an aperture in the side wall of the section rail and can be set against the partition with its end.
Claim 8
Dependent Claim
86 words
An arrangement as claimed in claim 6, having a recess opening into the underside of the section, wherein that side of the partition located next to the transverse element is provided with a through aperture coaxial with the transverse element and the aperture in the side wall of the section rail, and wherein the transverse element is provided at its end with a pin coaxial therewith and introducible into the aperture in the partition and adapted to be set against one side member of the ledge.
Claim 9
Dependent Claim
119 words
An arrangement as claimed in claim 1, having a transverse element consisting of parts telescopically engaging with each other, wherein the outer portion is provided with an axial slot starting from one of its ends and being of limited length, to whose one side short angular slots are connected, and wherein the inner portion is provided on one hand with a diametrically through slot starting from its inner end and being of limited length and on the other with a radially projecting pin which is introducible into the slots of the outer portion and adjustable by means of a wedge which can be driven into the slot of the inner portion between the end thereof and the outer portion.
Claim 10
Dependent Claim
55 words
An arrangement as claimed in claim 1, wherein the recess and the ledge is defined by upper first portion and a lower second portion having a parallelogram shaped cross section diverging outwardly in relation to the longitudinal middle plan of the seating furniture or seat, and an intermediate third portion having a rectangular cross section.
