## Abstract

A securement band for a head-mountable device can include a variable length strap, a first load spreader connected to the variable length strap, and a second load spreader connected to and separated from the first load spreader by the variable length strap. The first and second load spreaders can be fixed in length. The variable length strap can include elastic material and the first and second load spreaders can be rigid.

## Claims

### Claim 1

A securement band for a head-mountable device, comprising:
a variable length strap configured to connect to a housing of a display of the head-mountable device;
a first load spreader connected to the variable length strap and configured to be positioned on a first side of a user's head when donning the head-mountable device, the first load spreader comprising a housing defining an internal cavity; and
a second load spreader connected to and separated from the first load spreader by the variable length strap and configured to be on a second side of the user's head opposite the first side of the user's head when donning the head-mountable device.

### Claim 2 (depends on 1)

The securement band of claim 1, wherein the variable length strap comprises a first section and a second section, the first section extending between the first load spreader and the second load spreader.

### Claim 3 (depends on 1)

The securement band of claim 1, wherein the first load spreader defining a concave curved surface.

### Claim 4 (depends on 3)

The securement band of claim 3, further comprising an electronic component disposed within the internal cavity.

### Claim 5 (depends on 3)

The securement band of claim 3, further comprising an elastic buffer disposed on the concave curved surface.

### Claim 6 (depends on 5)

The securement band of claim 5, wherein the elastic buffer comprises foam.

### Claim 7 (depends on 5)

The securement band of claim 5, wherein the elastic buffer comprises a fluid-filled bladder.

### Claim 8 (depends on 1)

The securement band of claim 1, wherein the variable length strap comprises an elastic material.

### Claim 9 (depends on 1)

The securement band of claim 1, wherein the first load spreader and the second load spreader are rigid.

### Claim 10 (depends on 1)

The securement band of claim 1, wherein the first load spreader and the second load spreader are more rigid than the variable length strap.

### Claim 11

A head-mountable device, comprising:
a display;
a securement band connected to the display, the securement band comprising:
a first load spreader positioned on a first side of a user's head when donning the head-mountable device, the first load spreader defining an internal cavity;
a second load spreader positioned on a second side of the user's head when donning the head-mountable device; and
a band portion connecting and separating the first load spreader and the second load spreader.

### Claim 12 (depends on 11)

The head-mountable device of claim 11, wherein the first load spreader and the second load spreader each include a curved surface configured to conform to a head.

### Claim 13 (depends on 11)

The head-mountable device of claim 11, wherein:
the first load spreader is configured to press against a left side of a user's head; and
the second load spreader is configured to press against a right side of the user's head.

### Claim 14 (depends on 11)

The head-mountable device of claim 11, wherein the band portion includes a first portion and the head-mountable device further comprises:
a third load spreader disposed between the first load spreader and the second load spreader along a length of the securement band; and
a second band portion connecting and separating the second load spreader and the third load spreader.

### Claim 15 (depends on 14)

The head-mountable device of claim 14, wherein:
the first load spreader defines a first concave curved surface;
the second load spreader defines a second concave curved surface; and
the third load spreader defines a third concave curved surface having a curvature different than a curvature of the first concave curved surface and the second concave curved surface.

### Claim 16 (depends on 14)

The head-mountable device of claim 14, wherein the third load spreader is configured to press against a rear of a user's head.

### Claim 17

A load spreader, comprising:
a body comprising a housing defining:
a concave curved surface;
an internal cavity;
a strap engagement feature configured to connect the load spreader to the strap of a wearable electronic device and position the load spreader to contact a side of a user's head when donned; and
an electronic component disposed in the internal cavity.

### Claim 18 (depends on 17)

The load spreader of claim 17, wherein the concave curved surface comprises a curvature configured to conform to a head.

### Claim 19 (depends on 17)

The load spreader of claim 17, wherein the electronic component disposed in the internal cavity comprises at least one of a speaker, a sensor, and a microphone.
