A passenger seat for a passenger vehicle including but not limited to an aircraft may include a seat base, a seat back, and an energy absorption system. The energy absorption system is spherically coupled to the seat base and spherically coupled to the seat back, and includes a dampening member and a support assembly. The dampening member is movable relative to the support assembly responsive to a load applied on the seat back such that engagement between the support assembly and the dampening member dampens the load.

A carrycot is provided and includes a carrycot body, a mounting bracket, a first connecting assembly and a second connecting assembly. The mounting bracket is disposed on an outer surface of the carrycot body. The first connecting assembly is disposed on one of the carrycot body and the mounting bracket. The first connecting assembly is for detachably connecting the carrycot to a first carrier frame. The second connecting assembly is disposed on the mounting bracket and for detachably connecting the carrycot to a second carrier frame different from the first carrier frame. The advantages of the carrycot are simple structure and versatile use. Besides, a carrycot with integral and lightweight design is provided. Furthermore, a carrycot structure including the carrycot and a child carrier including the carrycot are provided.

A headrest may have at least one headrest body, a base support element, on which the headrest body is arranged such that the height can be adjusted and it can be locked in a height position, and a retaining element, with which the headrest body is arranged in a height-adjustable manner on the base support element. The retaining element can be detachably blocked in the adjusted height position. The retaining element engages through the base support element, and the retaining element is connected to the headrest body on both sides of the base support element. The headrest may also have a locking element for locking and unlocking the retaining element in the adjusted height position. The retaining element is guided in a height-adjustable manner on the base support element. A motor vehicle seat may have the headrest.
