Application No. 09/319,680
arrangement of the parts whereby the primary springs forming the foundation of the
cushion are reinforced, either directly or indirectly, by further resilient members which
may be of greater strength than the primary springs. Pockets are preferably provided
for the accommodation of the springs and a suitable fibrous material extends around
the pockets both between the same and between the outer covering of the cushion.
As shown in Figures 1-32 of Fischmann, primary springs 1 form the foundation of
a cushion and are attached directly to the frame of the cushion, where such a frame is
employed, but it is preferred to dispense with such frame and arrange the springs in
fabric pockets 2. The fabric pockets being surrounded by felt or other suitable fibrous
material 3 in such a manner that the internal construction of the cushion will be in the
form of a series of spring containing rolls A extending from side to side. The series of
rolls preferably being covered with a layer of fibrous material 4 between the same and
the outer covering or envelop 5.
Fischmann teaches (page 1, line 78, to page 2, line 7) that:
Where cushions are so provided with main or primary springs only,
especially where used in connection with automobiles, it is found that they work
very satisfactorily under ordinary conditions, but upon the vehicle passing over a
very uneven surface the violent shock will effect the total collapse of the cushion,
2 Figure 1 is a sectional perspective view of part of a cushion. Figure 2 is a sectional detail view
illustrating the primary spring within one of the pockets and a secondary spring concentrically disposed
within the primary spring and also provided with a pocket. Figure 3 is transverse section of Figure 2.
