Vibration device integrated into a seat
The present disclosure relates to a vibration device configured to be integrated into a vehicle seat and comprising a vibrator capable of generating vibrations. This device further comprises an attachment mechanism capable of attaching the vibrator to the back or underside of a support layer integrated into a member of the seat, and a damper which is in contact with this support layer and with the vibrator, and which is capable of reducing, in the support layer, the vibrations generated by the vibrator.
1. A vibration device configured to be integrated into a vehicle seat, the vibration device comprising
a vibrator capable of generating vibrations,
wherein the vibrator comprises an attachment mechanism capable of attaching the vibrator to the back or underside of a support layer integrated into a member of the seat, and a damper which is in contact with the support layer and with the vibrator, and which is capable of reducing, in the support layer, the vibrations generated by the vibrator.
2. The vibration device of claim 1 , wherein the attachment mechanism comprises a first member and a second member, and wherein the attachment to the support layer by the attachment mechanism is achieved by engagement of the first member with the second member, the vibrator being located between the support layer and the second member.
3. The vibration device of claim 2 , wherein the engagement of the first member with the second member is by snap-fitting.
4. The vibration device of claim 2 , wherein a portion of the support layer is sandwiched between the first member and the second member.
5. The vibration device of claim 4 , wherein the damper comprises a first separator and a second separator, the portion of support layer being sandwiched between the first separator and the second separator, the vibrator being located between the second separator and the second member.
6. The vibration device of claim 1 , wherein the support layer is composed of a set of parts chosen from a group comprising springs and rods.
7. A vehicle seat comprising at least one of the vibration devices according to claim 1 , in at least one of its members.
8. The vehicle seat of claim 7 , wherein it comprises two vibration devices placed one on the right half of the support layer and the other on the left half of the support layer, each of the vibration devices being capable of vibrating independently of one another.
9. The vehicle seat of claim 7 , wherein one member is the seating portion of the seat, the vibrator of at least one of the vibration devices being attached to the underside of the support layer.
10. The vehicle seat of claim 7 , wherein one member is the backrest of the seat, the vibrator of at least one of the vibration devices being attached to the back of the support layer.
