6 . The seatbelt assembly of claim 1 , wherein:

the chest section has a chest-section axis on which the chest section is elongated;

the shoulder section has a shoulder-section axis on which the shoulder section is elongated; and

the joint has a rotational axis that is transverse to the chest-section axis and the shoulder-section axis.

7 . The seatbelt assembly as set forth in claim 1 , wherein the chest section and the shoulder section extend from the shoulder belt in a body direction, the shoulder section is thinner than the chest section in the body direction.

8 . The seatbelt assembly as set forth in claim 1 , wherein:

the back includes an outer surface and an inner surface opposite the outer surface;

the distal ends of the legs are spaced from each other defining a cavity along the inner surface of the back; and

the shoulder belt abuts the outer surface of the back.

9 . The seatbelt assembly as set forth in claim 8 , wherein the coefficient of friction of the outer surface is less than the coefficient of friction of the inner surface.

10 . The seatbelt assembly as set forth in claim 8 , further comprising a removeable insert in the cavity.

11 . The seatbelt assembly as set forth in claim 1 , further comprising a fastener on the back, the fastener releasably engaging the shoulder belt.

12 . The seatbelt assembly as set forth in claim 1 , wherein the chest section is elongated in an upward direction along the axis from a bottom end to a top end, the shoulder section extending from the top end in the upward direction along the axis.

13 . The seatbelt assembly as set forth in claim 12 , wherein the joint is designed to be at a collar bone of a vehicle occupant.

14 . The seatbelt assembly as set forth in claim 1 , wherein the legs being the same length as each other from the back to the distal ends, respectively.

15 . A seatbelt attachment comprising:

a chest section having a chest-section axis on which the chest section is elongated;

a shoulder section having a shoulder-section axis on which the shoulder section is elongated; and

a joint connecting the chest section and the shoulder section, the joint being flexible relative to the chest section and the shoulder section;

the joint having a rotational axis that is transverse to the chest-section axis and the shoulder-section axis;

the shoulder section including a back elongated along the shoulder-section axis, the back including an outer surface and an inner surface opposite the outer surface;

the shoulder section including two legs elongated along the shoulder-section axis and aligned along the shoulder-section axis with the back, the legs each having a distal end and the legs extending from the back to the distal ends, respectively;

the distal ends of the legs being spaced from each other defining a cavity along the inner surface of the back; and

the coefficient of friction of the outer surface being less than the coefficient of friction of the inner surface.

16 . The seatbelt attachment of claim 15 , wherein the chest section includes a first foam core and the shoulder section includes a second foam core moveable relative to the first foam core about the joint; and

further comprising a covering over the first foam core and the second foam core, the joint being a portion of the covering between the first foam core and the second foam core.

17 . A seatbelt assembly comprising:

webbing including a shoulder belt elongated along an axis; and

a seatbelt attachment releasably engageable with the shoulder belt;

the seatbelt attachment including a chest section extending along the axis and a shoulder section extending along the axis;

the seatbelt attachment including a joint connecting the chest section and the shoulder section, the joint being flexible relative to the chest section and the shoulder section;

the shoulder section including a back elongated along the axis, the back including an outer surface and an inner surface opposite the outer surface;

the shoulder section including two legs elongated along the axis and aligned along the axis with the back, the legs each having a distal end and the legs extending from the back to the distal ends, respectively;

the distal ends of the legs being spaced from each other defining a cavity along the inner surface of the back;

the shoulder belt abutting the outer surface of the back; and

the coefficient of friction of the outer surface being less than the coefficient of friction of the inner surface.

18 . The seatbelt assembly as set forth in claim 17 , wherein the joint separates the chest section from the shoulder section along the axis.

19 . The seatbelt assembly of claim 17 , wherein the joint has a rotational axis that is nonparallel to the axis of the shoulder belt.

20 . The seatbelt assembly as set forth in claim 17 , wherein the joint is designed to be at a collar bone of a vehicle occupant.
