## Abstract

An armrest device for an aircraft seat has a cushion unit, which is at least substantially implemented by an elastomer and which is provided at least for forming an elastic substrate for an arm support for a passenger. The cushion unit has a comfort structure, which is provided for adjustment of an elastic deformability of the cushion unit.

## Claims

### Claim 1

An armrest device for an aircraft seat, and the armrest device includes a cushion unit forming an elastic base for an arm support for a passenger, wherein the cushion unit comprises:
at least an elastomer, and
a comfort structure, which is provided for adjustment of an elastic deformability of the cushion unit, wherein
the cushion unit is implemented by a silicone,
the comfort structure is implemented as a planar polygonal grid structure, and
the comfort structure forms honeycomb-shaped pockets that are adjacent to each other and implement the entire comfort structure or the comfort structure forms rectangular pockets that are adjacent to each other and implement the entire comfort structure.

### Claim 2 (depends on 1)

The armrest device according to claim 1, wherein the cushion unit comprises a support surface and the comfort structure is arranged on a side of the cushion unit that faces away from the support surface.

### Claim 3 (depends on 2)

The armrest device according to claim 2, wherein the comfort structure is implemented by a filigree structure.

### Claim 4 (depends on 2)

The armrest device according to claim 2, comprising a coating, which encompasses the cushion unit for protection.

### Claim 5 (depends on 2)

The armrest device according to claim 2, comprising an inlay, which is encompassed by the cushion unit.

### Claim 6 (depends on 5)

The armrest device according to claim 5, wherein the inlay is implemented by a high-temperature resistant material.

### Claim 7 (depends on 1)

The armrest device according to claim 1, wherein the comfort structure is implemented by a filigree structure.

### Claim 8 (depends on 1)

The armrest device according to claim 1, comprising a coating, which encompasses the cushion unit for protection.

### Claim 9 (depends on 1)

The armrest device according to claim 1, comprising an inlay, which is encompassed by the cushion unit.

### Claim 10 (depends on 1)

The armrest device according to claim 1, wherein the inlay is implemented by a high-temperature resistant material.

### Claim 11 (depends on 10)

The armrest device according to claim 10, wherein the inlay is implemented by a fiber-reinforced composite material.

### Claim 12 (depends on 1)

### Claim 13 (depends on 1)

A seat with an armrest device according to claim 1.

### Claim 14

An armrest device for an aircraft seat, and the armrest device includes a cushion unit forming an elastic base for an arm support for a passenger, wherein the cushion unit comprises:
at least an elastomer,
a comfort structure, which is provided for adjustment of an elastic deformability of the cushion unit, and
a support surface, wherein
the cushion unit is implemented by a silicone,
the comfort structure is formed by the cushion unit,
the comfort structure is arranged on a side of the cushion unit that faces away from the support surface, and
the comfort structure comprises pockets that are adjacent to each other.

### Claim 15

An armrest device for an aircraft seat, and the armrest device includes a cushion unit forming an elastic base for an arm support for a passenger, wherein the cushion unit comprises:
at least an elastomer, and
a comfort structure, which is provided for adjustment of an elastic deformability of the cushion unit, wherein
the cushion unit is implemented by a silicone,
