Padding for seats, in particular vehicle seats
View Patent ↗Padding for seats, in particular vehicle seats, has a padded body predetermining the contour of the padded surface, which can be changed. In order to adjust the padded surface contour to support the body of a seated person in an individual and orthopaedically correct manner, avoiding hardening of the padded surface which has an adverse effect on the seat comfort, the padded body is composed, at least in subregions, of a plurality of individual padded segments which are arranged next to one another and can be displaced relative to one another in the direction of the normal of the padded surface. Adjusting elements can displace the padded elements individually.
1. Padding for a seat, in particular a vehicle seat, comprising:
a padded surface,
a padded body predetermining a contour of the padded surface, and
means for changing the padded surface contour,
wherein the padded body is composed, at least in subregions, of a plurality of individual padded segments which are arranged next to one another and can be displaced relative to one another in a direction of the normal of the padded surface,
wherein the means for changing the padded surface contour have adjusting elements which displace the padded segments individually,
wherein a stiff base is arranged on an underside of each displaceable padded segment,
wherein the adjusting elements engage in each case on the base,
wherein each padded segment has a plurality of shaped pieces of padding material arranged next to one another, and
wherein the stiff base is formed by a box which is open on its side facing the padded surface and in which the shaped pieces are inserted in such a manner that they protrude over an edge of the box.
2. Padding according to claim 1 , wherein the shaped pieces are solid or hollow cylinders which are inserted into the box with cylinder axes orientated at right angles to a base of the box.
3. Padding according to claim 2 , wherein the padding material is a foam or rubberized hair.
4. Padding according to claim 2 , wherein the adjusting elements are flexible bellows which are filled with a fluid or gaseous medium, are supported in each case between a padded segment and a padding support holding the padded body, and are connected to a control device in order to change their filling volumes.
5. Padding according to claim 2 , wherein the adjusting elements are formed by controllable electric servomotors.
6. Padding according to claim 2 , wherein the padded body is covered by an upper padded layer of padding material, the upper padded layer is covered by a padding covering, and the upper padded layer is stitched loosely onto the padded body.
7. Padding according to claim 6 , wherein the upper padded layer is sewn onto the padding covering and the padding covering is clamped elastically to a padding support.
8. Padding according to claim 7 , wherein the padding covering has at least one peripheral edge zone of flexible material.
9. Padding according to claim 1 , wherein the padding material is a foam or rubberized hair.
10. Padding according to claim 1 , wherein the adjusting elements are formed by controllable electric servomotors.
11. Padding according to claim 1 , wherein the adjusting elements are flexible bellows which are filled with a fluid or gaseous medium, are supported in each case between a padded segment and a padding support holding the padded body, and are connected to a control device in order to change their filling volumes.
12. Padding according to claim 1 , wherein the padded body is covered by an upper padded layer of padding material, the upper padded layer is covered by a padding covering, and the upper padded layer is stitched loosely onto the padded body.
13. Padding according to claims 12 , wherein the upper padded layer is sewn onto the padding covering and the padding covering is clamped elastically to a padding support.
14. Padding according to claim 13 , wherein the padding covering has at least one peripheral edge zone of flexible material.
