Abstract

Simple and rigid attachment of a child seat to a vehicle seat that is not degraded by the seat'"'"'s cushioning is provided by a head rest fixture and two latch anchor fixtures combined by an operationally rigid frame structure. The frame structure has horizontal and vertical telescopically adjustable and lockable features to fit the system to varying dimensions of vehicle seats, head rests and child seat latch anchors. The child seat may be attached to the system via an object connecting structure that is combined with the frame structure via an in between damping element. The damping element opposes vehicle vibration eventually induced via the latch anchors on the operationally rigid frame from reaching the child seat.

Claims

1. A multipoint rigid attachment system for attaching an object to a vehicle having a seat with a head rest and a seat recessed latch anchor, said multipoint rigid attachment system comprising:

a. a head rest fixture comprising at least one of an anchor thorn and a head rest pole clamp configured to attach to a head rest attachment feature;

b. a latch anchor fixture that is configured to snap on said seat recessed latch anchor;

c. a frame structure combining said head rest fixture and said latch anchor fixture in a spacing that is bridging a backrest of said seat between said head rest and said seat recessed latch anchor while said head rest fixture being attached to said head rest fixture and while said latch anchor fixture being snapped on;

d. an object connecting structure combined with said frame structure for removably connecting said object with said frame structure above a surface shape of at least one of a backrest and a bottom rest of said seat;

wherein;

i. said anchor thorn comprises a configuration such that it is exchangeable with a pole of said head rest; and

ii. said head rest pole clamp comprises a configuration that is matching said pole for clamping said head rest pole clamp to said pole while said pole is inserted in a head rest anchor hole of said seat.

2. The multipoint rigid attachment system of claim 1, wherein said head rest pole clamp consists of a head rest pole bushing.

3. The multipoint rigid attachment system of claim 1, further comprising a pivoting joint in the vicinity of said head rest fixture such that said latch anchor fixture is snapped on in a pivoting motion around said pivoting joint while said head rest fixture is attached.

4. The multipoint rigid attachment system of claim 1, further comprising a top telescopic connection to telescopically adjust one of said anchor thorn with respect to one other of said anchor thorn and said head rest pole.

5. The multipoint rigid attachment system of claim 4, wherein said top telescopic connection is combined with a pivot joint such that said latch anchor fixture is snapped on in a pivoting motion around said pivoting joint while said first head rest fixture is operationally fixed.

6. The multipoint rigid attachment system of claim 1, wherein said frame structure further comprises a backrest bridging profile and a base profile substantially vertically telescopically adjustable and fixable with respect to each other.

7. The multipoint rigid attachment system of claim 6, wherein said object connecting structure is concentrically surrounding said base profile and attached to said base profile via a resilient element.

8. The multipoint rigid attachment system of claim 7, wherein said resilient element is configured as a vibration damper such that propagation of vehicle vibrations induced onto said frame structure are opposed onto said object connecting structure.

9. The multipoint rigid attachment system of claim 7, wherein said resilient element is configured as a torsion spring such that said object connecting structure is spring loaded held against rotating around a protrusion axis of said base profile.

10. The multipoint rigid attachment system of claim 9, wherein said protrusion axis is substantially vertical.

11. The multipoint rigid attachment system of claim 1, further comprising two of said latch anchor fixture, wherein said frame structure further comprises:

a. as part of said frame structure at least one of a backrest bridging profile and a telescopically adjustable profile combination, said telescopically adjustable profile combination including said backrest bridging profile and a base profile;

b. two latch arms configured for non destructively penetrating a contact fold between said backrest and said bottom rest;

c. two latch arm connectors each laterally connecting one of said two latch arms to said frame structure;

wherein each of two of said latch anchor fixture is positioned at a bottom end of said latch arm; and

wherein at least one of said two latch arm connectors is connected to a top end of said latch arm.

12. The multipoint rigid attachment system of claim 11, wherein said frame structure further comprises a horizontal telescoping fixture that is connected to said frame structure such that at least one of said latch arm connectors is horizontally telescopically adjustable and fixable.

13. The multipoint rigid attachment system of claim 1, wherein said object connecting structure is an integral part of a child safety seat.

14. The multipoint rigid attachment system of claim 1, wherein said object connecting structure is an integral part of a child safety seating frame.

15. The multipoint rigid attachment system of claim 1, further comprising a top telescopic connection to telescopically adjust one of head rest pole clamp with respect to one other of said head rest pole clamp.

16. The multipoint rigid attachment system of claim 15, wherein said top telescopic connection is combined with a pivot joint such that said latch anchor fixture is snapped on in a pivoting motion around said pivoting joint while said first head rest fixture is operationally fixed.
