An automotive head restraint apparatus includes a housing having a padded and upholstered exterior, the housing being rotatable about a lateral support tube that supports a lock plate having a lobe extending radially with a detent slot extending therein. A latch finger extends from a pivotable lock lever plate to releasably engage in the detent slot to latch the housing in the deployed position. A pull rod is secured to the lock lever plate, and is connected to a release lever arm at its other end. A shape memory alloy (SMA) wire loop is passed about a drive pulley that is supported by a reciprocally translatable slide. A drive arm extends from the slide to impinge on the release lever and raise the pull rod when the SMA wire loop is energized and contracted, thereby releasing the latch finger to rotate the housing to the retracted position.

A headrest device and a chair having the same are provided. The headrest device includes a support frame, a headrest component and a reset member. The support frame is pivotally connected with the headrest component, and the reset member is connected with the headrest component and configured to drive the headrest component to rotate relative to the support frame. The support frame is provided with a limiting convex block, and the limiting convex block can stop a rotation of the headrest component when the headrest component moves to an initial limiting position.

A method for manufacturing a vehicle seat backrest comprises the steps of: providing first and second uprights of a backrest frame and a support member of an upper backrest adjustment device; positioning the first upright partly facing a first side face of the support member and the second upright partly facing a second side face of the support member; moving the first upright relative to the second upright along a transverse direction of the support member, in order to sandwich the support member such that the support member of the upper backrest adjustment device is mounted on the first and second uprights of the backrest frame so as to pivot about a transverse axis.

A headrest for a vehicle with improved collision performance includes: a headrest stay provided integrally with a seat back and exposed at an upper end of the seat back; a blower connected to the headrest stay; and a rotation direction change member installed between the headrest stay and the blower, connecting the headrest stay and the blower, and configured to allow a rotation direction of the headrest stay and a rotation direction of the blower to be opposite to each other in an event of a rear collision.

A vehicle interior system including a first seat assembly, disposed within a vehicle cabin, a first sensor, a second sensor, and a controller is provided. The first and second sensors may each be disposed within the vehicle cabin. The first sensor may be configured to obtain first signals indicative of a positioning of an obstacle within a predetermined coordinate system. The second sensor may be configured to obtain second signals indicative of a positioning of the first seat assembly within the predetermined coordinate system. The controller may be configured to receive the signals from the first sensor and to map a portion of the obstacle based on the first signals and relative to a portion of the first seat assembly within the predetermined coordinate system.
