## Abstract

A protective helmet includes a helmet shell, a support cage, and a securing device for securing the support cage to the helmet shell. An impact absorption device is arranged between the support cage and the helmet shell.

## Claims

### Claim 1

A protective helmet comprising:
a helmet shell;
a support cage:
a first securing device for securing the support cage on the helmet shell;
a second securing device for securing a component other than the support cage to the helmet shell; and
an impact absorption device disposed between the support cage and the helmet shell;
wherein the second securing device aids in positioning the impact absorption device.

### Claim 2 (depends on 1)

The protective helmet according to claim 1, wherein the impact absorption device is in part positively arranged on the helmet shell or the support cage.

### Claim 3 (depends on 1)

The protective helmet according to claim 1, wherein the impact absorption device is in part non-positively arranged on the helmet shell or the support cage.

### Claim 4 (depends on 1)

The protective helmet according to claim 1, wherein the impact absorption device comprises a substantially plastic deformation behavior responsive to an impact on the helmet shell.

### Claim 5 (depends on 1)

The protective helmet according claim 1, wherein the impact absorption device composes a plurality of cavities, at least a first cavity separated from a second cavity by a wall.

### Claim 6 (depends on 5)

The protective helmet according to claim 5, wherein the pluralities of cavities comprises a plurality of tubes.

### Claim 7 (depends on 6)

The protective helmet according to claim 6, wherein the plurality of tubes comprises an extruded copolymer.

### Claim 8 (depends on 6)

The protective helmet according to claim 6,
wherein a first tube of the plurality of tubes comprises a first inner wall and a first outer wall, the second tube of the plurality of tubes comprises a second inner wall and a second outer wall, the first outer wall being in contact with the second outer wall; and
wherein the first inner wall is thicker than the first outer wall or the second inner wall is thicker than the second outer wall.

### Claim 9 (depends on 6)

The protective helmet according to claim 6,
wherein a first tube of the plurality of tubes comprises a first inner wall and a first outer wall, the second tube of the plurality of tubes comprises a second inner wall and a second outer wall, the first outer wall being in contact with the second outer wall; and
wherein the first outer wall and the second outer wall are connected by heat.

### Claim 10 (depends on 1)

The protective helmet according to claim 1, wherein the impact absorption device comprises Koroyd.

### Claim 11

(canceled)

### Claim 12 (depends on 1)

The protective helmet according to claim 1, wherein the second securing device prevents the impact absorption device from shifting between the helmet shell and the support cage.

### Claim 13 (depends on 1)

The protective helmet according to claim 1, wherein the first securing device is designed so that the support cage assumes an end position with respect to the first securing device in a used state of the protective helmet, and the support cage applies a force to the impact absorption device in an end position to prevent movement of the impact absorption device between the helmet shell and the support cage.

### Claim 14 (depends on 1)

The protective helmet according to claim 1, wherein the impact absorption device comprises a plurality of grooves forming ventilation channels together with the helmet shell on a side of the impact absorption device facing the helmet shell.

### Claim 15 (depends on 14)

The protective helmet according to claim 14, further comprising openings in the helmet shell, the ventilation channels communicate with the openings.
