A seat back (35) with a headrest (40) on a vehicle seat (33). To reduce the whiplash effect during a front-end accident to a significant degree, the head rest (40) rests on a headrest support (38) that can be pivoted outward and forward around a horizontal axis (39), with the backward displacement of the support being restricted in terms of movement.

An apparatus to prohibit user injury from sudden impact or rotational or whiplash movement. The apparatus includes a helmet, a body harness configured to secure to the user, a plurality of tethers and a plurality of spools. Each tether has one end attached to the helmet and an opposing end fixed relative to the body harness. Each spool is positioned with a tether in wound engagement with the spool.

The present invention affords a headrest airbag for reducing or preventing whiplash and / or head injuries related to vehicle collisions. The headrest airbag is comprised of a trim material that encloses a headrest member, a receiving means for receiving an exchangeable gas bag module and an exchangeable gas bag module at least partially inserted into the receiving means. The exchangeable gas bag module is comprised of an inflatable gas bag and a gas generator for inflating the gas bag. The gas bag maintains its location within the receiving means of the headrest airbag whether it is inflated or not. The inflated gas bag reduces the distance that a head of a driver or passenger is thrown in a rearward direction before coming into contact with a headrest, and reduces the force of such an impact.

A vehicle seat capable, with a simple, lightweight structure, of improving a whiplash moderation effect from a head rest. In the vehicle seat (10), when there is an impact at a rear face of the vehicle, a support frame (50) that is fixed to a reclining rod (46) separately from a seatback frame (32) supports the waist area of a seat occupant from the vehicle rearward side. Thus, a load from the seat occupant that is inputted to the seatback frame (32) is reduced. Therefore, a displacement amount (deformation amount) of the seatback frame (32) to the vehicle rearward side may be suppressed. Thus, a duration until the head area of the seat occupant abuts against a headrest (16) may be shortened. Moreover, the support frame (32) that only supports the waist area of the seat occupant need only be fixed to the reclining rod (46). Therefore, a simple, lightweight structure may be formed.

An essential oil reclaim method for use with a corresponding apparatus, comprising the following steps: the apparatus grabs the tree parts, the tree tops or the tree limbs, and shakes them with rotating drums provided with chains (under whiplash effect); the needles are segregated through a vibrating sieve; the needles are compressed for a first essential oil extraction under mechanical compression; the needles are then pushed into a sealed chamber comprising an endless screw which upwardly conveys the needles; steam is sprayed on the needles, so as to thermally extract essential oils from condensate; the needle residues, or “muka”, escapes from the top end of the thermal chamber. This essential oil reclaim apparatus also relates to the invention.

The invention provides a vehicle seat preventing whiplash injury and belongs to the technical field of vehicle safety. A stretch control unit is arranged in a headrest and is capable of responding before collision and driving a stretch protecting pillow to extend rapidly, and the stretch protecting pillow stops when contacting with the head immediately; during collision, the distance between the pillow and the head is shortened through the extension of the stretch protecting pillow, the horizontal shifting of the head and neck is reduced, and the backward whiplash effect of the head is reduced. A buffering energy absorption damping rebound unit is arranged between a base and the backrest, during collision, under the effect of inertia, the human back produces a backward stress on the backrest and performs deflection displacement between the base and the backrest, under the effect of buffering energy absorption, the deflection kinetic energy and deflection speed of the backrest are decreased, the backrest rebounds when being threw to the limit, the rebounding speed of the backrest is decreased under the damping effect, and the forward head whiplash effect is reduced accordingly.

The invention relates to a headrest (10) for a vehicle seat, in particular for a backrest of a motor vehicle seat, said headrest essentially comprising a headrest frame or headrest casing (14) and a foam base body (36) that surrounds the headrest frame or casing (14). In the event of a rear impact on the motor vehicle, the headrest remains fixed in relation to the backrest (conventional headrest)or at least part of the headrest is immediately displaced towards the vehicle occupant (active headrest). According to the invention, the head of a vehicle occupant can be brought into contact with the headrest (10) at least at two different heights (k1z, k2z), (two-point contact), to reduce or neutralise a torque (My) about a y-axis (y-y) in the vicinity of the vertebral column and to prevent accident-related injuries to the seat occupant, in particular to prevent cervical spine syndrome or a whiplash injury in the event of a front and / or rear impact. A head centre of gravity (HCG) is also configured between the two heights (k1z, k2z) of the headrest (10).

Considering a case where a patient with whiplash syndrome can sleep safely, it is when the patient is sleeping at an appropriate orientation, whereby if a pillow enabling sleep while maintaining an appropriate orientation exists, a sick person can sleep peacefully, and furthermore, the pillow may be useful in treating the whiplash syndrome. A pillow enabling the patient with whiplash syndrome to sleep peacefully is thus developed.A pillow 1 of the present invention has a deformable pillow body 2 including an upper surface cloth 21 and a lower surface cloth 22 having an edge cloth 23 as a boundary, formed with a head depression part 4 including a bottom surface 41 at a position depressed from the upper surface cloth 21 to the lower surface cloth 22 of the pillow body 2, and a groove part 6 extending from the head depression part 4 to the edge cloth 23 of the pillow body 2 and being formed by joining the upper surface cloth 21 to the lower surface cloth 22.

A reduced-impact-and-recoil headrest that includes a ratchet mechanism, allowing components to incrementally translate with respect to each other. The reduced-impact-and-recoil headrest includes an exterior housing surface that is deformable, providing cushioning for a vehicle occupant's head. The headrest also includes an interior compartment within the housing, with the ratchet mechanism disposed within the interior compartment. The headrest is configured to decrease the force of a collision experienced by the occupant, thereby decreasing the likelihood and severity of traumatic brain injuries resulting from the occupant's head striking a stationary headrest. Instead, the reduced-impact-and-recoil headrest is configured to incrementally move with the occupant's head, providing an incremental cushion for the occupant's head. The ratchet mechanism also prevents the reduced-impact-and-recoil headrest from automatically translating back to its pre-impact position, thereby decreasing the occupant's risk of ligament tear and whiplash.
