The supporting structure has individual strand-type or strip-type supporting parts (13) with a pre-defined flexibility. A second supporting structure in the form of padding is arranged on the first supporting The padding has a flexibility that is different from that of the supporting parts (13) of the first supporting structure, and at least the supporting structures are provided with an outer coating structure. ## Claims ### Claim 1 A head rest of a seat, especially of an air passenger seat, comprising: a load-bearing structure that can be attached to a seatback part of the seat; a first support structure for support of the head of a seat occupant, wherein the first support structure is made up of individual band-like support parts of a predetermined flexibility; a second support structure designed as a cushion part arranged on the first support structure, wherein the second support structure has a differently selected flexibility compared to the first support structure, and an outside covering structure that at least partially covers both the first support structure and the second support structure. ### Claim 2 (depends on 1) The headrest according to claim 1, wherein the load-bearing structure has a middle part that extends laterally, can be anchored to the seatback part, and includes two lateral endings and a side part at each of the lateral endings that protrudes in a forward direction, and wherein the band-like support parts of the first support structure overlap both the middle part and the side parts at least in partial areas. ### Claim 3 (depends on 2) The headrest according to claim 2, wherein the middle part of the load-bearing structure is made up of a cross member that extends laterally relative to a balance of the load bearing structure, and a support bar extends from a central area of the cross member, wherein the support bar is adapted to extend towards and connect with a seatback part of the seat, and wherein the side parts, which are located on both lateral ends of the cross member, extend forward while spreading slightly apart. ### Claim 4 (depends on 2) The headrest according to claim 2, wherein the band-like support parts of the first support structure, partially overlap one another and extend in different directions, and wherein the band-like support parts are provided at least in the areas of the middle part and the side parts of the load-bearing structure that are provided for the support of the head. ### Claim 5 (depends on 4) The headrest according to claim 4, wherein at least one band-like support part, of the first support structure is continuous from one side part to the other side part along the middle part of the load bearing structure. ### Claim 6 (depends on 5) The headrest according to claim 5, wherein at least a cushion element that makes up a support surface for one of the band-like support parts is provided on each of the side parts of the load bearing structure. ### Claim 7 (depends on 6) The headrest according to claim 6, wherein at a location of a supporting area, at which the head of the seat occupant is supported, a mechanical load from the head of the seat occupant is applied to a multi-layer arrangement that consists of the outside covering structure, one of the support parts of the first support structure and one of the cushion elements. ### Claim 8 (depends on 1) The headrest according to claim 1, wherein the second support structure that is arranged on the first support structure is made up of at least one cushion part, which covers the first support structure at least in an area that is designed for the support of the head and that is directly adjacent to the first support structure. ### Claim 9 (depends on 8) The headrest according to claim 8, wherein the outside covering structure is directly adjacent to the at least one cushion part that makes up the second support structure. ### Claim 10 (depends on 1) The headrest according to claim 1, wherein at a location of a supporting area, at which the head of the seat occupant is supported, a mechanical load from the head of the seat occupant is applied to a multi-layer arrangement that consists of the outside covering structure, the cushion part and one of the support parts of the first support structure. ### Claim 11 (depends on 1) The headrest according to claim 1, wherein the outside covering structure provides a holding-force by frictional adhesion to resist sliding of the head of a sleeping seat occupant.
