Process for producing a supporting shell for a seat
First Claim
1. A process for producing a supporting shell for a seat having at least one pad, which supporting shell forms a supporting substructure for at least one of a seating surface and a backrest of the seat, the process comprising the acts of:
- a) providing a measuring mat on a seat frame comprising a planar, non-cushioned contact surface in a region of the seating surface and/or backrest, the measuring mat being flexible in space;
b) seating a test subject down on the measuring mat, and fixing in place a three-dimensional surface contour of the measuring mat produced by the act of sitting down;
c) determining geometric data of the three-dimensional surface contour of the measuring mat;
d) releasing the fixed three-dimensional surface contour of the measuring mat;
e) repeating the acts of seating, determining and releasing with different test subjects; and
f) superimposing the three-dimensional surface contours resulting from the measurements carried out with different test subjects onto each other, and deriving the three-dimensional surface contour of the supporting shell therefrom.

Abstract
A supporting shell for a seat is provided by carrying out in-seat measurements with a plurality of test subjects, wherein the test subjects sit down on a measuring mat placed on a neutral seat frame. The measuring mat has a readily displaceable filling and adapts to the contour of the body of the respective test subject. After the test subject has sat down on the measuring mat and before the test subject leaves the same, the filling inside the measuring mat is fixed in place by applying a negative pressure. The geometric data of the surface contour of the measuring mat are determined and stored for each test subject. The measured surface contours are then superimposed onto one another. This produces an average surface contour which can subsequently be further altered slightly for adaptation to large seat users, and therefore a modified surface contour is created as a basis for the production of the supporting shell of the seat.

10. A process for producing a cushion support for a seat, which cushion support serves as a support on a supporting substructure for at least one of a seating surface and a backrest of the seat, the process comprising the acts of:

19. A seat comprising:
-
a supporting shell having at least one pad, the supporting shell forming a supporting substructure for at least one of a seating surface and a backrest of the seat; a seat frame comprising a planar, non-cushioned contact surface in a region of the seating surface and/or backrest; a measuring mat disposed on the seat frame, the measuring mat being flexible in space such that substantially when a test subject sits down on the measuring mat, the measuring mat contours to a shape of the test subject that contacts the measuring map; and a delivery device that is structurally configured to exert and maintain a negative pressure within the measuring mat, the negative pressure maintaining the contoured shape of the test subject on the measuring mat after the test subject no longer contacts the measuring mat;
whereinthe seat has the at least one pad arranged on a side of the supporting shell oriented toward a seat user, wherein the pad comprises cushioning properties. - View Dependent Claims (20)
