Definitions
- This invention relates to cushions in general and more specifically it relates to certain new and useful resilient bodies which serve for supporting the human body and for other purposes.
- my present invention is related to cushion means which serve as seat and/ or back members for vehicle seats and for any other purposes in which a resilient cushion means may be requested or desired, and it has for an important object thereof the provision of a novel and improved cushion means of the character referred to above, by which a quite comfortable support is attained by the combination of a lower resilient assembly comprising a plurality of coil compression working springs evenly arranged on and supported by a base member, and of an upper compound cover assembly comprising a relatively thin layer of sponge rubber or similarly soft material and screen meansjarranged substantially between the upper ends of said coilsprings and the lower surface of said layer so as to uniformly distribute the uplifting pressures localized on the spaced upper ends of said coil springs on the whole surface of said cover assembly.
- the resilient cushion member for covering the seat frame structure and for direct supporting of the human body comprises a lower resilient assembly in which the resilient means is formed by a plurality of coil springs evenly arranged in spaced relationship and designed to resiliently support a cover member upon a rigid plate of a frame base member, connected to or more integral with the said seat frame structure.
- Said cover member is designed to give to the supported human body a comfortable lift and to avoid that the said spaced coil springs may exert on the oversitting human body a plurality of perceptible uplifting pressures localized on the tips of any or of the most loaded coil spring.
- said cover member is made in the form of a substantially thick layer of felt, textile material, fabric, leather and the like, having a certain tensionresisting character and an inherent softness.
- Said conventional cover members are subject to the common objection that the cushion is made heavy, pretty expensive, and air-tight and that moisture, water and perspiration The air-tightness of said conventional cover members makes the seat uncomfortable in the summer time, in torrid zones and the like.
- Said one-piece cushions are, however, subject to some objections in view of expensiveness, of excessive softness and poor progressive lifting power, and of poor stability of the supported load, the upper surface of said one-piece cushions being subject to laterally move and to bend in any direction.
- an object of this invention is the provision of a novel and improved seat cushion compound member in which, according to the combination above touched upon, a relatively thin upper cover member of sponge rubber or like material is supported by a plurality of spaced coil springs through a flexible and tension resistentmedium layer, such as a metallic screen for example, the said medium forming a pressure resistent surface upon which the said localization of the spaced resting points actuated by the several spaced coil spring tips are not perceptible by the oversitting human body.
- cushion means produced according to this invention and comprising the above said substantial combination of elements may find other useful applications, such as back cushion for seats, for example.
- Another object of the invention is the provision of a seat cushion of the type described in which the amount of sponge rubber required in the manufacture thereof is greatly reduced in respect to the amount comprised in said one-piece seat cushions.
- a still other object of the invention is the provision of an article of manufacture of the character described in which an outer cover means of fabric or other tension resisting and pliable material is provided to connect the outline of said upper sponge rubber cover member to the outline of the said base member, for giving the desired shape to the Whole cushion, confining its raising when unloaded and preventing undue distortion thereof.
- a further object of the invention is the provision of a seat cushion produced by said combination and in which an ample space beneath the cover member, a cover member made of sponge-like material, and other useful features allowing a full ventilation and cooling of the cushion are provided, so that said cushion may be advantageously used in the summer time, in torrid zones and warm climate and/ or conditions.
- a still further object of this invention is the provision of a seat cushion in which by applying the above said novel and advantageous combination a remarkable saving in weight of the article of manufacture is attained, thus making said cushion suitable for airplanes and all other fields of practical use in which weight saving is most desired.
- An important object of the invention is also the provision of a novel method of manufacture of seat cushions of the character referred to above, comprising the steps of making said screen medium layer integral with the upper sponge rubber cover member by vulcanization thereof.
- Figure 1 is a perspective'longitudinal sectional view of a preferred form of embodiment of this invention, actuating a seat cushion suitable for vehicles, for example, and provided with a back cushionv of like construction;
- Figure 2 is a perspective transverse sectional view of a modified form of embodiment of the invention.
- Figure 3 is a perspective exploded view of the combination of elements comprised in the form of embodiment shown in said Fig. 2.
- numeral 19 indicates the base member and numeral 11 the plurality of compression working coil springs arranged on and supported by said base member, for springably supporting the cover member forming the outer load supporting surface of the cushion.
- a base member 10 constructed in the form of a wooden frame, although a metallic frame, a plate member and any other structure known to those skilled in the art may be made use of, if desired.
- the plurality of coil springs may be directly connected to and supported by a base forming element integral with or forming part of the seat or the chair structure, for example.
- any single spring will be preferably arranged side by side to the adjacent ones, and the use of inter-linked coil springs will be particularly advantageous.
- An arrangement of springs in which the end loops of the coil-forming wire are positioned on the lower ends only is desirable, so that the upper portions of said springs present to the superimposed cover compound members a smooth and nonprojecting netlike surface.
- the seat cushion in combination with the said assembly, comprising member 10 and a plurality of springs 11, the seat cushion comprises a compound cover member having an upper layer 12 and a lower layer 13, according to the basic combination and arrangement shown in Fig. 1.
- the said upper layer 12 is made of a material of preferably great softness, light weight and permeable to air, such as for example sponge rubber. Other materials may be moreoverused in producing said upper layers, provided that a suitable resiliency is attained, plain or alveolate rubber, resilient plastics and so on.
- the inherent softness of. said upper layer.12 makes the contact with the upper surface thereof comfortable.
- the said lower layer. 13 is designed to form a'medium I through which the weight of the load, and in particular the human body weighing down on said upper layer 12, is transmitted to the coil spring members arranged there beneath.
- said lower layer 13 is made of a metallic network or screen formed by a'plurality of intercrossing and closely spaced steel wires, for example, or
- the said screen made or equivalent lower layer 13 may made or equivalent upper layer 12 by any suitable means, by adhesive tape, for example.
- the connection may be made on the periphery of said lower layer 13 or on a plurality of positions spaced along said periphery.
- the said lower layer is constructed in the form of a metallic screen 13 and it is made integral with the said upper layer, .by embodying said screen 13 in the lower portion of the sponge rubber couch 13' forming said upper layer during the moulding and vulcanizingthereof.
- the sponge rubber member forming the said upper layer is provided with downturned edge portions 14 to shape the outer surface of the cushion in the desired conventional peripherically rounded shape and to provide the seat and/or the back cushion thereof with a smooth and resilientout-lining.
- the said down-turned portions 14 may be downwardly extended until the edge thereof may contact with and be connected to the edge of the base member 10, if desired, or said portions may be limited to the rounded portion of outer surface of the cushion, as shown.
- a compound cover member according to this invention isperipherally connected to the under placed base member by tension resisting and collapsible means, for protection of the assembly of springs and to give to the cushion its desired shape, the said tension resisting means limiting the upward movement of said cover member when the cushion is unloaded.
- said connecting means are formed by a fabric strip arranged about the cushion and connected either to the periphery of the said base member and of said compound cover'member.
- I provide a seat cushion according to the invention with a complete textile covering means 15, adhering to the whole outersurface of upper layer and downwardly extending thereabout withportions 16, the lower edges of which are nailed'or otherwise firmly connected to the peripheral portion of base member 10.
- the zone of said portions 16, comprised'between the edge of base member'ltl and the lower edge of down-turned extensions .14.of upper member 12, are fully collapsible as said compound cover member gets 'lower'under the load.
- a seat produced according to the invention is particularly suitable for vehicle use.
- The'outer surface, upon which the human body rests, is smooth and soft and provides a comfortable supporting and contacting surface.
- the reduced thickness. of the soft material prevents any transverse deformation and movement of said surface under the dynamic effect of vehicles acceleration and abrupt slowing down (said deformation and movementbeing a serious disadvantage to which conventional one-piece seat cushions are subject).
- main spring system formed by the plurality of coil springs gives a properly progressive uplift so that felt or other poorly-wearing material is not required in the construction. 7 p
- a piece of unvulcanized or partially vulcanized rubber is put into a vulcanizing mould between a fabric forming the outer covering 15 and a screen forming the medium layer 13.
- the vulcanizing step is'then performed and by said step the said screen is embedded or incorporatedinto the rubber near the lower surface thereof and the fabric is also embedded in the same rubber adjacent to its upper surface.
- the compound article thus produced. is .then placed upon the. assembly comprising base member ltland the plurality of springs 11, and the outer portions of fabric are connected to the periphery of said base member.
- a seat cushion of the character described will be completed and finished by applying, according to current knowledge, a leather, or plastic, or fabric protective and/or ornamental covering, which may be glued or otherwise connected to or made integral with outer covering 15, 16, if desired.
- the outer covering or coverings and the upper layer may be substantially perforated, the screen formed lower layer allowing full air to flow through all superimposed strata, so that the resiliency and the comfortableness of the seat are not adversely affected.
- a seat cushion comprising, in combination, a rigid base member, a plurality of coil spring members uniformly arranged and spaced on said base member, each of said springs having one end thereof connected to said base member; and a resilient member extending substantially over the entire base member and being supported by the free ends of said coil spring members, said resilient member including a layer of foam plastic material and a metallic screen secured thereto over at least one face unattached to said rigid base.
- a seat cushion comprising, in combination, a rigid base member, a plurality of coil spring members uni forrnly arranged and spaced on said base member, each of said springs having one end thereof connected tc said base member; and a resilient member extending substantially over the entire base member and being supported by the free ends of said coil spring members, said resilient member including a layer of foam rubber material and a metallic screen vulcanized thereto over at least one face unattached to said rigid base.
