Abstract
The present invention involves a vehicle seat and headrest arrangement for use with a seat having a seatback in a vehicle. The vehicle seat and headrest arrangement comprises a headrest arrangement including a headrest, at least one impact target, and at least one of a guide member and a follower. The seatback has at least one of the other of a guide member and follower. The guide member has a guideway and the follower engages the guideway of the guide member such that upon impact to the vehicle a rearward load by the occupant upon the impact target will cause the follower to engage the guideway in such a manner as to cause the headrest to be moved in a first manner and a second manner so as to support the head of an occupant.
Claims25
A vehicle seat and headrest arrangement for use with a seat having a seatback in a vehicle, the vehicle seat and headrest arrangement comprising:
- a headrest arrangement including a headrest, an impact target, and one of a guide member and a follower;
- the seatback having the other one of a guide member and follower, the guide member having a guideway and the follower extending laterally and engaging the guideway of the guide member such that upon impact to the vehicle a rearward load by the occupant upon the impact target will cause the follower to engage the guideway in such a manner to cause the headrest to be moved in a first manner and a second manner to support a head of an occupant.
A vehicle seat and headrest arrangement for use with a seat having a seatback in a vehicle, the vehicle seat and headrest arrangement comprising:
- a headrest arrangement including a headrest and a headrest extension, the headrest extension having one of a guide member and a follower and an impact target located below the one of a guide member and a follower;
- a seatback frame of the seatback having side members and an upper cross frame member, the upper cross frame member having the other of a guide member and follower, the guide member having a guideway and the follower extending laterally and slidingly engaging the guideway of the guide member such that upon impact to the vehicle a rearward load by an occupant upon the impact target will cause the follower to be slidably guided by the guideway such that the headrest is moved in a first manner and a second manner.
A vehicle seat and headrest arrangement for use with a seat having a seatback in a vehicle, the vehicle seat and headrest arrangement comprising:
- a headrest arrangement including a headrest, a headrest extension extending from the headrest, a laterally extending follower fixedly connected to the headrest extension, and an impact target located below the follower;
- a seatback frame of the seatback having side members and an upper cross frame member, the upper cross frame member having a guide member fixedly connected to the cross frame member through which the follower extends, the guide member having a guideway and the follower slidingly engaging the guideway of the guide member such that upon impact to the vehicle a rearward load by an occupant upon the impact target will cause the follower to be slidably guided by the guideway such that the headrest is moved in a first manner and a second manner.
A seat and headrest arrangement for use in a vehicle comprising:
- a headrest arrangement including a headrest, an impact target, and one of a guide member and a follower;
- and
- a seatback having the other one of a guide member and follower, the guide member having a guideway and the follower engaging the guideway such that upon impact to the vehicle a rearward load by the occupant upon the impact target will cause the follower to engage the guideway to cause the headrest to be moved in a first manner and a second manner to support a head of an occupant;
- wherein the guide member is a bushing having a cam configuration and the follower is a cam such that engagement of the cam and cam configuration together with a forward momentum of the headrest causes the headrest to move in the first manner and the second manner.
