Definitions

  • the present invention relates to an upholstered piece of seating furniture with an insert element and a method for producing such an inlay element and a method for changing the seat contour of an upholstered piece of seating furniture.
  • Office chairs are usually mass-produced in large numbers in series, in particular to be economical.
  • the basic components of each type of chair are manufactured uniformly, as is usual in series production.
  • the anatomy of the human body that the office chairs are supposed to carry is very different, if only because of the respective gender.
  • parameters important for ergonomics such as body weight or different body proportions, add to the diversity of potential users.
  • An office chair designed for a tall and heavy person, for example the 90th percentile man cannot guarantee an ergonomic sitting position equally for a small and light person, for example the 10th percentile woman.
  • this range of users cannot usually be adequately served with current office chair concepts in terms of comfort and health, especially with regard to the upholstery surfaces.
  • Custom-made products Office chairs are extremely unusual and usually hardly affordable from an economic point of view.
  • the object of the present invention is to provide a piece of seating furniture that can be customized and has a changeable seat contour in accordance with a person's needs.
  • this object is achieved by a piece of seating furniture having the features of patent claim 1, by a manufacturing method having the features of patent claim 11 and/or by a method having the features of patent claim 14.
  • the idea on which the present invention is based is to provide an upholstered piece of seating furniture with adjustable and/or replaceable insert elements, so that a user can adjust the seating contour of the upholstered piece of seating furniture according to his or her wishes and/or anthropometric conditions.
  • Data about wishes and/or anthropometric conditions which can be based on medical data, among other things, can already be provided when ordering the upholstered Seating furniture to be sent to the manufacturer.
  • the upholstered seating furniture can be equipped with the appropriate insert elements ex works and sent to the customer. The customer thus receives a piece of seating furniture individually assembled or tailored by the insert elements.
  • the manufacturer can largely use the comparatively inexpensive and quality-assuring series production, especially for the support structure, the upholstery and the upholstery cover of the seating furniture.
  • the seat contour can thus be individually adjusted by the insert elements based on the series-produced piece of seating furniture.
  • Predefined receiving areas on the useful side of the supporting structure allow the essentially uniform seating furniture to be individually adapted using insert elements that are produced in different sizes or individually and are fixed in the receiving areas.
  • different insert elements are provided that differ in their geometry and padding properties, such as foam properties, degree of hardness or the like.
  • different clothing sizes predetermined for certain body size ranges are conceivable, which can be selected, for example, on the basis of measured body features.
  • the insert elements can alternatively or additionally be designed to fit different body size ranges and individually positioned over a large adjustment range. In this way, an optimal adaptation of the contour is made possible.
  • individual insert elements are also conceivable, which can be produced in a user-specific manner in terms of geometry and padding properties, for example based on an impression or a measurement of the user's individual body.
  • the insert elements can also be retrofitted or exchanged. Since comfort requirements and body measurement values can change over time, it is thus possible to introduce or remove additional insert elements in the seating furniture.
  • the seating furniture can also be used by other people.
  • the designation of upholstered seating includes, in particular, membrane chairs, meeting, seminar and conference chairs and lounge furniture.
  • seat contour refers to the contour of the entire useful side of the chair, in particular the seat, the backrest and the headrest of the chair.
  • the lordosis area is that area of a person's back that is shaped forwards by the curvature of the lumbar/cervical spine according to the medical definition of a lordosis. For backrests, this essentially corresponds to the lower half of the backrest if the backrest extends at least to the neck area.
  • the insert element is detachably fastened to the receiving area.
  • it can be releasably attached using a form-fitting and/or force-fitting fastening means.
  • the insert element can be detached from the receiving area using at least one of the following fastening means fastened: plug connection, screw connection, Velcro, mushroom in mushroom connection, press studs, zipper, magnetic connection, stretch cover.
  • the upholstery cover can be designed as a stretch cover and the insert element can be fastened by tensioning the upholstery cover.
  • the cover on the backrest surface is opened via two laterally running zippers and the insert element is pushed in laterally.
  • the insert element When the zippers are closed, the padding element is held in place by the tension of the upholstery cover.
  • the insert element can be attached and exchanged in the receiving area in a simple and reversible manner.
  • the form-fitting and/or non-positive fastening means mentioned generally do not require any further fastening materials or aids and can be effectively fastened quickly and easily.
  • the insert element is non-detachably attached to the receiving area by means of a form-fit fastening means, in particular by means of at least one of the following fastening means: riveted connection, welded connection; seam connection; adhesive connection.
  • a form-fit fastening means in particular by means of at least one of the following fastening means: riveted connection, welded connection; seam connection; adhesive connection.
  • the upholstery cover has an opening, in particular one closable opening, which is designed and arranged with respect to the respective support structure in order to insert an insert element from the outside into the receiving area and/or to remove an insert element fixed in the receiving area.
  • the opening is provided, for example vertically, with a predominantly longitudinal extent on at least one lateral side of the support structure, being arranged essentially at the height of the receiving area of the useful side.
  • the opening can also be provided continuously from a first lateral side via an upper side or a lower side to a second lateral side, so that the cushion cover can be completely or partially removed from the support structure.
  • the opening can have closure means, which can be designed in particular as a Velcro fastener, snap fasteners, buttons, a zipper, magnetic connection or combinations thereof.
  • closure means can be designed in particular as a Velcro fastener, snap fasteners, buttons, a zipper, magnetic connection or combinations thereof.
  • two zips are attached to the side of the backrest surface, which can open the upholstery cover vertically over the entire surface.
  • the insert element is then pushed in laterally and positioned using a scale that is applied to the receiving area, for example in the form of a second underlying cover with a velor layer. In this way, the position of an installed insert element can be changed or the installed insert element can be exchanged for another insert element or several insert elements.
  • the insert element is at least partially elastic in such a way that a rear side of the insert element, when fixed in the receiving area, has the shape of the receiving area. This ensures that the insert element is attached in a non-slip manner and no excessive loads act on the insert element in the event of incorrect attachment in the receiving area.
  • an insert element almost completely covers the entire useful side of the backrest and/or seat surface, so that an additional padding layer is created.
  • the insert element has at least two areas with different elasticity and/or compressibility. In this way, more sensitive areas of the human body can be made softer with the aid of greater elasticity and/or compressibility of the insert element. In contrast, adjacent more supportive areas of the human body may have less elasticity and/or compressibility of the insert member to provide more support to the human body in those areas.
  • the different elasticity and/or compressibility of the insert element is realized at least by one of the following measures: different thickness; material cuts; different material thickness; and different material densities
  • the insert elements can have a multi-layer structure composed of a wide variety of materials.
  • different types of additional covers for the insert element and/or different types of support plates connected to the insert element can be provided for this purpose.
  • the insert element which is made of foam, for example, covered with a textile, material mix, or the like, like a pillow. This creates another factor that can be used to change the characteristics of the insert element.
  • the insert elements are attached to a felt material that serves as a carrier plate for the insert element in order to increase rigidity.
  • the insert elements can be glued to the felt material, for example.
  • Velcro strips can also be sewn on for attachment. It is also conceivable to adjust the properties by adding other materials such as plastics, metals, wood, etc., for example in the form of pocket springs made of wire or the like.
  • the insert element contains one or more spring pockets.
  • an air cushion can be provided which changes the contour when it is inflated.
  • insert elements can be designed to adapt to an individual contour, for example with a viscoelastic material and a vacuum device. This means that an impression of the back section can be created using the viscoelastic material and then kept in the respective shape by vacuuming.
  • the insert element has a large number of segments which are arranged in particular in a matrix-like manner with respect to one another.
  • the segments can be square or round or square and round in shape.
  • the segments can be arranged, for example, axially symmetrically to the central axis of the insert element, but are not tied to any symmetries and can also be freely arranged relative to each other.
  • the plurality of segments can be provided in many different sizes and configurations in the insert member.
  • the insert element is provided in the lordosis area and/or in the headrest area of the backrest.
  • the lumbar region of the lower back and the headrest area are particularly sensitive areas, so that insert elements attached in these areas can efficiently increase the well-being and health of a person in relation to the remaining areas of the seating furniture.
  • the insert element is provided in the seat surface.
  • the greatest weight usually rests on the seat surface when a person is sitting on it in the intended seating positions.
  • misalignment of the spine and/or pelvic obliquity can be counteracted by appropriate insert elements in the seat.
  • preferred seating positions can also be supported with the help of insert elements.
  • an insert element can also be provided with a recess and/or an area with a particularly soft material. For example, the coccyx area can be relieved in this way.
  • the intermediate space has a padding at least in sections, with the padding having a recess in the receiving area for inserting the insert element.
  • the insert element can quickly and easily at exactly the intended position in the upholstery. In particular, this facilitates the assembly of the insert element and also avoids incorrect positioning of the insert element on the support structure.
  • the insert element can essentially correspond to the surface of the cushion on the useful side or protrude from the surface of the cushion on the useful side.
  • the insert element can also be provided attached directly to the padding in the receiving area, for example fastened by friction with an upholstery cover designed as a fitted cover.

  • a foam raw material in particular from PUR, PE, crosslinked PE, PA granules or foams and combinations thereof as foam raw material.
  • additional medical data of the person in particular taking into account musculoskeletal disorders, and/or the person's anthropometry and/or comfort requirements of the person are used or taken into account for the step of creating the computer-aided data record.
  • the insert elements can be manufactured specifically in such a way that they meet medical requirements and/or meet the individual wishes of a single person.
  • the insert elements are thus also able to be used in the medical treatment of, in particular, musculoskeletal disorders.
  • the method comprises the steps of: releasing a first insert element fixed in the receiving area of the supporting structure of the piece of seating furniture; removing the detached first pad member through the opening of the cushion cover; providing a second panel member having a different property from the first panel member, wherein the moving comprises inserting the second panel member and the fixing comprises securing the second panel member.
